✦ Synopsis

C-Coumarinoyl-N-arylformohydrazonoyl bromides (3) were synthesized by reaction of Nnitrosoarylacetamides with an appropriate sulfonium bromide in ethanol at room temperature. The reactions of potassium thiocyanate, potassium selenocyanate, thiourea, methyl phenylthiocarbomate, and methyl phenylhydrazinedithioate with hydrazonoyl bromide 3a were examined.
