In recent years, interesting phys. and chem. properties of graphene oxide (GO) have led to a great deal of excitement in the chem. One of the most promising results is the use of GO and the functionalized GOs as heterogeneous catalysts in organic synthesis. In this work, GO was functionalized with piperazine (GO-NH), converted to magnetic GO-NH by incorporating Fe₃O₄ particles into GO-NH (Fe₃O₄@rGO-NH), and then reduced with hydrazine hydrate to yield piperazine-grafted magnetic reduced graphene oxide (Fe₃O₄@rGO-NH). The obtained Fe₃O₄@rGO-NH was used as a heterogeneous catalyst in the Gewald three-component reaction between some aldehydes or ketones, sulfur, and malononitrile or Et cyanoacetate. The catalyst showed good activity for various starting materials, easy separation from the reaction mixture using an ordinary magnet and reusability. Also, the catalyst was used six times without significant loss of activity. In the experiment, the researchers used many compounds, for example, 2-Amino-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile (cas: 70291-62-2Application of 70291-62-2).

Cyanation of Aryl Bromides with K₄[Fe(CN)₆] Catalyzed by Dichloro[bis{1-(dicyclohexylphosphanyl)piperidine}]palladium, a Molecular Source of Nanoparticles, and the Reactions Involved in the Catalyst-Deactivation Processes was written by Gerber, Roman;Oberholzer, Miriam;Frech, Christian M.. And the article was included in Chemistry – A European Journal in 2012.Synthetic Route of C6H5NS This article mentions the following:

Dichloro[bis{1-(dicyclohexylphosphanyl)piperidine}]palladium [(P{(NC₅H₁₀)(C₆H₁₁)₂})₂PdCl₂] (1) is a highly active and generally applicable C-C cross-coupling catalyst. Apart from its high catalytic activity in Suzuki, Heck, and Negishi reactions, compound 1 also efficiently converted various electronically activated, nonactivated, and deactivated aryl bromides, which may contain fluoride atoms, trifluoromethane groups, nitriles, acetals, ketones, aldehydes, ethers, esters, amides, as well as heterocyclic aryl bromides, such as pyridines and their derivatives, or thiophenes into their resp. aromatic nitriles with K₄[Fe(CN)₆] as a cyanating agent within 24 h in NMP at 140 鎺矯 in the presence of only 0.05 mol % catalyst. Catalyst deactivation processes showed that excess cyanide efficiently affected the mol. mechanisms as well as inhibited the catalysis when nanoparticles were involved, owing to the formation of inactive cyanide complexes, such as [Pd(CN)₄]^2-, [(CN)₃Pd(H)]^2-, and [(CN)₃Pd(Ar)]^2-. Thus, the choice of cyanating agent is crucial for the success of the reaction because there is a sharp balance between the rate of cyanide production, efficient product formation, and catalyst poisoning. For example, whereas no product formation was obtained when cyanation reactions were examined with Zn(CN)₂ as the cyanating agent, aromatic nitriles were smoothly formed when hexacyanoferrate(II) was used instead. The reason for this striking difference in reactivity was due to the higher stability of hexacyanoferrate(II), which led to a lower rate of cyanide production, and hence, prevented catalyst deactivation processes. This pathway was confirmed by the colorimetric detection of cyanides: whereas the conversion of 灏?solvato-浼?cyanocobyrinic acid heptamethyl ester into dicyanocobyrinic acid heptamethyl ester indicated that the cyanide production of Zn(CN)₂ proceeded at 25 鎺矯 in NMP, reaction temperatures of >100 鎺矯 were required for cyanide production with K₄[Fe(CN)₆]. Mechanistic investigations demonstrate that palladium nanoparticles were the catalytically active form of compound 1. In the experiment, the researchers used many compounds, for example, 3-Methylthiophene-2-carbonitrile (cas: 55406-13-8Synthetic Route of C6H5NS).

3-Methylthiophene-2-carbonitrile (cas: 55406-13-8) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion.Synthetic Route of C6H5NS

A new method for the preparation of cyclic nitriles by catalytic degradation. I was written by Houben, J.;Fischer, Walter. And the article was included in Berichte der Deutschen Chemischen Gesellschaft [Abteilung] B: Abhandlungen in 1930.Computed Properties of C11H11N This article mentions the following:

The trichloromethyl ketimides of the type described in the preceding abstract are smoothly converted not only by alc. and aqueous alkali but also catalytically in Et₂O by small amounts of powd. KOH into cyclic nitriles and CHCl₃ without the alkali being in any way attacked. With the ketimides of the free phenols, where the HO group must be saturated with alkali before cleavage can take place, it is difficult to determine the amount of alkali required for the cleavage, but it is believed that here, too, the process is catalytic. A procedure has been developed which permits of converting the ketimide directly, without purification, into the nitrile and also of separating the ketimide from the accompanying ketone. The method almost always gives good yields and has thus far failed in no case. Thus, from p-MeC₆H₄C(:NH)CCl₃ (85% pure), allowed to stand 2-4 hrs. under petroleum ether with powd. CaO and KOH (powd. under petroleum ether and dried over P₂O₅ at 100鎺?, was obtained 75% p-MeC₆H₄CN which, while it did not solidify until cooled to 0鎺? yielded only p-MeC₆H₄CO₂H with acids and then alkali, and p-MeC₆H₄CONH₂ with MeOH-HCl. It is not clear what caused the depression of the m. p. of the MeC₆H₄CN. The crude mixture of 2,4-Me₂C₆H₃C(:NH)CCl₃ (91%) and ketone obtained from m-xylene and CCl₃CN gives with powd. KOH-CaO 82% 2,4-Me₂C₆H₃CN, m. 24-5鎺?

3H-Azepines and related systems. Part 5. Photo-induced ring expansions of o-azidobenzonitriles to 3-cyano- and 7-cyano-3H-azepin-2(1H)-ones was written by Lamara, Kaddour;Redhouse, Alan D.;Smalley, Robert K.;Thompson, J. Robin. And the article was included in Tetrahedron in 1994.HPLC of Formula: 64113-86-6 This article mentions the following:

Unlike other aryl azides bearing electron-withdrawing ortho-substituents, o-azidobenzonitriles on photolysis in aqueous-tetrahydrofuran yield mixtures of the expected 3-cyano- (I; R=CN, R¹ = R² = H) and the unexpected 7-cyano-3H-azepin-2(1H)-ones (I; R = R¹ = H, R² = CN). In one instance ring-contraction to 2-azabicyclo[3.2.0]hept-6-en-3-one II is noted. X-Ray crystallog. data for 7-cyano- (I; R = R¹ = H, R² = CN) and 4-chloro-7-cyano-3H-azepin-2-one (R = H, R¹ = Cl, R² = CN) , and for the azabicycloheptenone, are presented. In the experiment, the researchers used many compounds, for example, 5-Methyl-2-nitrobenzonitrile (cas: 64113-86-6HPLC of Formula: 64113-86-6).

5-Methyl-2-nitrobenzonitrile (cas: 64113-86-6) belongs to nitriles. The R-C-N bond angle in and nitrile is 180鎺?which give a nitrile functional group a linear shape. Both the carbon and the nitrogen are sp hydridized which leaves them both with two p orbitals which overlap to form the two 锜? bond in the triple bond. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).HPLC of Formula: 64113-86-6

Solid-state fluorescence properties of small iminocoumarin derivatives and their analogues in the coumarin series was written by Abid-Jarraya, Nihel;Khemakhem, Kacem;Turki-Guermazi, Hamida;Abid, Souhir;Saffon, Nathalie;Fery-Forgues, Suzanne. And the article was included in Dyes and Pigments in 2016.Recommanded Product: 51473-74-6 This article mentions the following:

Considering the many potential applications of fluorescent materials, dyes that exhibit emission in the solid state are in high demand, especially if they are easy to prepare and inexpensive. In this respect, exploring the behavior of basic iminocoumarins seemed relevant. The spectroscopic properties of 3-cyano-7-diethylamino-2-iminocoumarin and a derivative bearing an ethoxycarbonyl group were therefore studied in the solid state, and a comparison was made with the corresponding coumarin. The three compounds had very close fluorescence properties in solution In contrast, the coumarin derivative was much more emissive in the solid state than the iminocoumarins. This discrepancy was tentatively related to the crystal packing modes. A comparison was made with 7-diethylaminocoumarin to clarify the role of the cyano group, which may not be advantageous from a spectroscopic viewpoint. Using a solvent-exchange method, the three cyano compounds generated elongated microparticles, the substituted iminocoumarin derivative even led to flat microfibers. This work shows that small coumarins are valuable solid-state fluorescent dyes while small iminocoumarins should be used as building blocks to access more elaborated compounds if solid-state applications are envisaged. In the experiment, the researchers used many compounds, for example, 7-(Diethylamino)-2-oxo-2H-chromene-3-carbonitrile (cas: 51473-74-6Recommanded Product: 51473-74-6).

7-(Diethylamino)-2-oxo-2H-chromene-3-carbonitrile (cas: 51473-74-6) belongs to nitriles. The electronic structure of nitriles is very similar to that of an alkyne with the main difference being the presence of a set of lone pair electrons on the nitrogen. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.Recommanded Product: 51473-74-6

Cone angle of ligands – Group IV and V compounds was written by Imyanitov, N. S.. And the article was included in Koordinatsionnaya Khimiya in 1985.Category: nitriles-buliding-blocks This article mentions the following:

The cone angle (the steric characteristic, expressing the degree of filling out by the ligand of the coordination sphere) was calculated for 610 ligands. The ligands considered have the formulas AX₃ or A(OX)₃ and have tetrahedral geometry with respect to A in the fragment of the complex M-AX₃ (M = coordinating metal; A = N, P, As, Sb, Bi, C, Si, Ge, Sn, Pb; X = alkyl, cycloalkyl, aryl, alkylaryl, arylalkyl). Known cone angles of ligands based on P, determined by mol. models, are correlated; the effective covalent and van der Waals radii of X were calculated with respect to the known cone angles. The cone angles are calculated with respect to the radii and the internuclear M-A distances. This procedure ensures standardization and comparability of the steric characteristics obtained. Cone angles are equal or nearly equal for neighboring elements of group IVA and VA. As the at. number of A in a group increases the cone angle decreases. The change in cone angle was considered in relation to the M-ligand; the cone angle values, established for Ni complexes, can be used for complexes of all other transition metals, except those in the beginning of the transition series. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Category: nitriles-buliding-blocks).

3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. The electronic structure of nitriles is very similar to that of an alkyne with the main difference being the presence of a set of lone pair electrons on the nitrogen. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.Category: nitriles-buliding-blocks
