Abstract:  By the reaction of benzoyl and 2-furoyl isothiocyanates, respectively, with acetone phenylhydrazone 5-benzoylimino- and 5-(2-furoylimino)-2,2-di- methyl-4-phenyl-l,3,4-thiadiazolines, respectively, were formed. The reaction with benzaldehyde phenylhydrazone resulted in benzaldehyde 2-phe- nyl-4-acylthiosemicarbazones, while that with acetophenone and ben- zophenone phenylhydrazones, respectively, did not proceed at all. The u.v., i.r., mass, 1H-n.m.r., and 13C-n.m.r. spectra are discussed.
