Sigalov UDC 547~ 2'314.2:543.422 2-Acylmethyl-5-phenyl-and 3-acylvinyl-2-acylmethyl-5-phenyl-l,3,4-thiadiazol-4ines were obtained by the reaction of terminal a-acetylenic ketones with thiobenzhydrazide. Substituted acetylenic ketones react with thiobenzhydrazide in alcohol to give N,S-bis(acylvinyl)thiobenzhydrazides. 'V a)c IIA liB a R=Ph, RL=H;b R=R~=Ph; cR=~-C4H3S, W=H; dR==-C.dlaS, R~=Ph
