Abstract

Abstract5‐Cyano‐2H‐thiopyran and a number of derivatives have been obtained in fair to good yields by heating compounds with the system CCCSCCCN in silicon oil; 4‐cyano‐2‐methylthiophenes are formed by heating these systems in dimethylsulfoxide in the presence of diisopropylamine. The starting systems were prepared by nucleophilic addition of 2‐propynethiol, HCCCH2SH, to cyanoalkynes RCCCN (R  H or alkyl).
