The reaction of hydrazide with carbony] chloride in the presence of sodium carbonates leads to the corresponding 1,2- diacylhydrazines [1a-t, R 1C(O)NHNHC(O)R2, R1 = aryl, R2 = aryl or alkyl] in moderate to excellent yield (57-90%). The latter reacts with 2,4-diphenyl-l,3-diselenadiphosphetane- 2,4-diselenide (Woollins' reagent, WR) in refluxing toluene to give a series of new 2,5-disubstituted 1,3,4-selenadiazoles (2a-t, 51-99% yield). All compounds were characterized spectroscopically and six compounds were characterized crystalloqraphically. Wiley-VCH Verlag GmbH & Co. KGaA.
