摘要

Three pathways were observed in the reactions of Schiff bases of Thiohydrazides with P(NR₂)₃,. (a) MeS-R₂N exchange: MeS-C(=S)-NHN=CHPh (1) reacted with P(NR₂)₃ led to new Schiff bases, R₂N-C(=S)-NHN=CH=Ph (2). (b) Cleavage of C=S bond and the formation of P=S bond: H₂N-C(=S)-NHN=CH=Ph (3) reacted with P(NR₂)₃ gave rise to the thiophosphoric amide, (Et₂N)₂P(=S)-NH-CH=N-N=CH-Ph (4). (c) Formation of thiadiazole and triazole: Schiff bases 2a and H₂N(MeS)C=N-N=CH-Ph (6) reacted with P(NR₂)₃ respectively and produced 5-dimethylamino-2-phenyl-2,3-(2H)-1,3,4-thiadiazole (5) and 5-methylthio-2-phenyl-2,3-(2H)-1,3,4-triazole (7).
