摘要：

N-Phenyl- and N-benzyl thiosemicarbazide 1a,b reacted with tetracyanoethylene (TCNE) viacharge-transfer (CT) complex formation giving thiadiazepine and thiadiazole derivatives (6. 7 and 16). On mixing la,b with 2.3 -dichloro-5,6-dicyano-1,4 -benzoquinone (DDQ), oxathiadiazoles and dithiadiazole derivatives (20 and 24) were formed. The mechanism of the formation of these products has been elucidated.
