A convenient method for the α-carbethoxylation of alkylnitriles was written by Albarella, James Paul. And the article was included in Journal of Organic Chemistry in 1977.Name: 2-Cyclohexylacetonitrile This article mentions the following:
Treatment of RCH2CN (R = C3-16 alkyl) in THF at -78° with 2.3 molar equiv LiN(CHMe2)2 followed by 1.02-1.05 molar equiv (EtO)2CO or ClCO2Et gave excellent yields of the resp. RCH(CN)CO2Et. Similarly prepared were Et 2-cyano-2-cyclopentylacetate and the cyclohexyl analog. In the experiment, the researchers used many compounds, for example, 2-Cyclohexylacetonitrile (cas: 4435-14-7Name: 2-Cyclohexylacetonitrile).
2-Cyclohexylacetonitrile (cas: 4435-14-7) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. 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.Name: 2-Cyclohexylacetonitrile
