2,3-Dihydro-1,3,4-thiadiazoles and triazolino[4,3-a]pyrimidines containing benzofuran moiety were prepared from reaction of 1-bromo-2-(5-chlorobenzofuranyl) ethanedione-1-phenylhydrazone with each of potassium thiocyanate, alkyl carbodithioates and pyrmidine-2-thiones. All newly synthesized were confirmed by elemental analysis, spectral data, and alternative route synthesis whenever possible.

Abstract Unsymmetrical azines were synthesized from reaction of C-coumarinoyl-N-arylformohydrazonoyl bromide with different alkyl carbodithioates. In addition, reactions of hydrazonoylhalides with thioanilide and methyl dithioates were studied. The structures of newly synthesized compounds were confirmed by elemental analyses, spectroscopic tools, and alternative syntheses whenever possible.
A novel series of bis(1,3,4-thiadiazole) derivatives were synthesized in one step methodology with good yields by condensation reaction between bis-hydrazonoyl chloride 1 and various reagents. The structures of the prepared compounds were confirmed by spectral data (IR, NMR, and MS), and elemental analysis. The anticancer activity against human breast carcinoma (MCF-7) cancer cell lines was evaluated
