Davis, Roman et al. published their research in Journal of Organic Chemistry in 1981 | CAS: 4435-14-7

2-Cyclohexylacetonitrile (cas: 4435-14-7) 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. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Reference of 4435-14-7

Direct one-step conversion of alcohols into nitriles was written by Davis, Roman;Untch, Karl G.. And the article was included in Journal of Organic Chemistry in 1981.Reference of 4435-14-7 This article mentions the following:

Primary, secondary, and tertiary alcs. (10 compounds) are converted into the corresponding nitriles by treatment with two equivalent of NaCN-Me3SiCl and a catalytic amount of NaI in DMF-CH3CN. The reactions are complete in 2-8 h. Except for cyclohexanol, the yields range from 75-98%. Evidence is presented which demonstrates that SN2 and SN1 processes are obtained and a common bis-silyloxonium intermediate is suggested. In the experiment, the researchers used many compounds, for example, 2-Cyclohexylacetonitrile (cas: 4435-14-7Reference of 4435-14-7).
