Abstract: Using 1,3-diphenylacetone as precursor, bibenzyldithiolmethane(1) was prepared through reacting 1,3-diphenylacetone with dry hydrogen sulfide and hydrogen chloride. Under microwave irradiation, compound 1 was subjected to esterification and hydrazinolysis to yield 1,1-bibenzyl-1,1-bimercaptoacetyl-hydrazine(3). The condensation reactions between compound 3 and aromatic aldehyde led to the production of a series of 1,1-bibenzyl-1,1-bimercaptoacetylhydrazone(4a～4n). Their structures were confirmed by IR, 1H NMR, MS and elemental analysis.

Key words: microwave irradiation., acetylhydrazone, synthesis
