✦ Synopsis

Reactions of Ph2C3 dianion with alkyl thiocyanates or ethylene 1,2-dithioeyanate give 1,3bis(alkylthio)allenes or tetrathiacyclic bisallene, respectively. Thermal reactions of 1,3bis(benzylthio)allene and tetrathiacyclic bisallene afford 2,3,5-uiphenylthiophene and 1,2-bismethylidene cyeiobutane derivatives, respectively.
