Abstract
Thiocarbamoylation of hydrazones of aromatic aldehydes with tetramethylthiuram disulfide (TMTD) afforded diarylaldazines, 4,4-dimethylthiosemicarbazide, and 5-dimethylamino-1,3,4-thiadiazole-2-thiol. In addition, the reaction of TMTD with salicylaldehyde hydrazone yielded symmetrical thiocarbonyldihydrazone of salicylaldehyde, whereas the reactions withp-bromobenzaldehyde andm-nitrobenzaldehyde hydrazones affordedp-bromo-N,N-dimethyl-andN,N-dimethyl-m-nitrothiobenzamides, respectively. Possible pathways of formation of the resulting products are discussed.
