On July 19, 2013, Cao, Ying; Zhang, Song-Chen; Zhang, Min; Shen, Guang-Bin; Zhu, Xiao-Qing published an article.Product Details of 2510-01-2 The title of the article was Determination of Thermodynamic Affinities of Various Polar Olefins as Hydride, Hydrogen Atom, and Electron Acceptors in Acetonitrile. And the article contained the following:

A series of 69 polar olefins with various typical structures (X) were synthesized and the thermodn. affinities (defined in terms of the molar enthalpy changes or the standard redox potentials in this work) of the polar olefins obtaining hydride anions, hydrogen atoms, and electrons, the thermodn. affinities of the radical anions of the polar olefins (X•-) obtaining protons and hydrogen atoms, and the thermodn. affinities of the hydrogen adducts of the polar olefins (XH•) obtaining electrons in acetonitrile were determined using titration calorimetry and electrochem. methods. The pure C=C π-bond heterolytic and homolytic dissociation energies of the polar olefins (X) in acetonitrile and the pure C=C π-bond homolytic dissociation energies of the radical anions of the polar olefins (X•-) in acetonitrile were estimated The remote substituent effects on the six thermodn. affinities of the polar olefins and their related reaction intermediates were examined using the Hammett linear free-energy relationships; the results show that the Hammett linear free-energy relationships all hold in the six chem. and electrochem. processes. The information disclosed in this work could not only supply a gap of the chem. thermodn. of olefins as one class of very important organic unsaturated compounds but also strongly promote the fast development of the chem. and applications of olefins.

On September 5, 2005, Basurto, Sara; Garcia, Susana; Neo, Ana G.; Torroba, Tomas; Marcos, Carlos F.; Miguel, Daniel; Barbera, Joaquin; Ros, M. Blanca; de la Fuente, M. Rosario published an article.Application of 2510-01-2 The title of the article was Indene and pseudoazulene discotic liquid crystals: A synthetic and structural study. And the article contained the following:

Several new liquid-crystalline indene and pseudoazulene systems are reported. These mols. give rise to either columnar hexagonal mesophases and/or columnar plastic phases. The unique nature of these compounds stems from their nonclassical discotic structure. Although the mols. have rigid aromatic cores, they lack terminal tails and instead the polarizable atoms (S, halogens) or polar groups (CN, CO) act as unusual soft parts. From many structurally related materials, for this type of compound mol. stacking in the solid state is a prerequisite for the appearance of a columnar mesophase, although other intermol. interactions within the layers are also important in establishing liquid-crystalline order. The behavior reported for these mesomorphic mols. opens up new possibilities in the search for related mol. interactions that might be useful for the construction of supramol. architectures with particular properties. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Application of 2510-01-2

Thus, 2-cyclopropyl-1-trifluoromethylbenzo[b]thiophenium triflate was prepared by reacting 1-cyclopropylethynyl-2-trifluoromethylsulfanylbenzene with trifluoromethanesulfonic acid. When Me 1-indanone-2-carboxylate was treated with 2-cyclopropyl-1-trifluoromethylbenzo[b]thiophenium triflate, 1-oxo-2-trifluoromethylindan-2-carboxylic acid Me ester was obtained. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Category: nitriles-buliding-blocks
