N,N-Dimethylpyridin-4-Amine Mediated Protocol for Cyanoethoxycarbonylation of Aldehydes Under Solvent-Free Conditions

N,N-Dimethylpyridin-4-amine (DAMP) (10 mol%) was successfully employed as catalyst for cyanoethoxycarbonylation of aromatic and aliphatic aldehydes at room temperature under solvent free condition to give corresponding ethylcyanocarbonates in excellent isolated yield (up to 95%) in 15–90 min. Simple experimental conditions and product isolation procedure has made this protocol quite attractive for the synthesis of ethylcyanocarbonates in an environment-friendly manner.

Cyanoethoxycarbonylation of aldehydes was carried out in presence of N,N-dimethylpyridin-4-amine (DAMP) (10 mol%) as catalyst. The excellent yield (up to 95%) of ethylcyanocarbonates was achieved in 15–90 min under solvent-free condition at room temperature.
