New method for the synthesis of α-chlorocinnamonitriles

Nenajdenko,Shastin,Golubinskii,Lenkova,Balenkova

, p. 228 - 232 (2007/10/03)

A novel method for the preparation of nitriles of α-chlorocinnamic acid from aldehydes and ketones was proposed. Transformation of carbonyl compounds into hydrazones followed by treatment of the reaction mixture with CCl3CN in the presence of copper chloride(I) yields α-chlorocinnamonitriles.
