Efficient Preparation of 2,3-Disubstituted Cyclopropane-1-Carbonitriles via Selective Decarboxylation of 1-Cyanocyclopropane-1-Carboxylates

Abstract

2,3-Disubstituted cyclopropane-1-carbonitriles were efficiently formed via a selective decarboxylation reaction of substituted 2-aroyl-3-aryl-1-cyano-cyclopropane-1-carboxylates in up to 92% yield. The structures of three typical compounds were confirmed by X-ray crystallography.
