Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. 105-34-0, formula is C4H5NO2, Name is Methyl 2-cyanoacetate. Both routes are green in the sense that they do not generate stoichiometric amounts of salts. Category: nitriles-buliding-blocks.
Shen, Yuqing;Yuan, Chaoping;Zhu, Xianyi;Chen, Qin;Lu, Shenjun;Xie, Haibo research published 《 Engineering cellulose into water soluble poly(protic ionic liquid) electrolytes in the DBU/CO2/DMSO solvent system as an organo catalyst for the Knoevenagel condensation reaction》, the research content is summarized as follows. Herein, linear water soluble cellulosic poly(protic ionic liquid) (CPIL) electrolytes were facilely and atom economically prepared after the dissolution of cellulose in the newly developed DBU/CO2/DMSO solvent system, followed by the simple addition of succinic anhydride under mild conditions. The DBU not only participated in the dissolution of cellulose as a solvent component, but also acted as an organo catalyst for the acylation reaction of cellulose with succinic anhydride, as well as cation component in the targeted CPIL electrolytes. The reaction was optimized, and the effect of the reaction conditions on the chem. and phys. properties of the CPILs was investigated. The CPIL electrolyte aqueous solution was successfully used as the catalytic reaction media for the Knoevenagel condensation reaction. It was found that the reaction was homogeneous at the beginning, and the products could precipitate out from the media with the proceeding of the reaction, thus affording satisfactory filtration yields ranging from 56.7% to 93.8%. The solution properties of the CPIL aqueous solution were primarily investigated towards an in-depth understanding of the catalytic mechanism, by which a synergetic catalytic mechanism of the CPILs was proposed, and the reaction started with a nucleophilic addition reaction, and was then followed by a fast dehydration reaction. Finally, the direct reusability potential of the CPIL aqueous solution after the product filtration was also primarily investigated for the Knoevenagel condensation reaction.
Category: nitriles-buliding-blocks, Methyl cyanoacetate is an alkyl cyanoacetate ester.
Methyl cyanoacetate is the intermediate product in pharmaceutical organic synthesis as well as in the synthesis of some biologically active compounds used in agriculture. It undergoes calcite or fluorite catalyzed Knövenagel condensation with aromatic aldehydes, giving the corresponding arylidenemalononitriles and (E)-α -cyanocinnamic esters.
Methyl Cyanoacetate is often used as a nucleophile in the electrochemical oxidation of catechols. Methyl Cyanoacetate is also a reagent in the synthesis of Methyl 2-Amino-4-trifluoromethylthiophene-3-carboxylate (M287290); a compound used in the synthesis of DPP-IV inhibitors for treating type 2 diabetes., 105-34-0.
