Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 591769-05-0, Name is 3-Cyclopentylacrylonitrile, molecular formula is C8H11N, belongs to nitriles-buliding-blocks compound, is a common compound. In a patnet, author is Satyanarayana, Iddum, once mentioned the new application about 591769-05-0, Recommanded Product: 3-Cyclopentylacrylonitrile.
Nitromethane as a surrogate cyanating agent: 7-N,N-dimethylamino-4-hydroxycoumarin-catalyzed, metal-free synthesis of alpha-iminonitriles
An efficient, metal/alkali-cyanide free approach for the synthesis of alpha-iminonitriles via kinetically controlled, base-mediated and 1,3-diketone-catalyzed reaction is reported. The preparation of target compounds was realized by condensation of substituted anilines and aldehydes in nitromethane as a surrogate cyanating agent and as a solvent. This strategy was further improved by replacing aldehydes and nitromethane with beta-nitrostyrene and ethanol, respectively, rendering the methodology greener. The catalytic role played by 1,3-diketones such as 7-N,N-dimethylamino-4-hydroxycoumarin in this three-component reaction was investigated, and a plausible mechanism was proposed based on control experiments.
