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