Hydrazonoyl chlorides 1 reacted with 2-aryl-1-cyano-1-thiazol-2-ylethenes 2 in presence of triethylamine to give the cycloadducts 4. which were converted to the corresponding pyrazoles 5 by the action of sodium methoxide. The reaction of hydrazonoyl halides 1 and 6 with each of 2-arylidene-2-cyanoethanethioamides 7 and 2-arylhydrazono-2-cyanoethanethioamides 14 in ethanolic triethylamine or ethanolic sodium hydroxide solutions, has been investigated. Structures of all the products were established on the basis of their spectral data and alternative synthesis.

The reactions of hydrazidoyl halides with N-phenylcyanothioacetamide and α-cyanothioacetamide gave unexpected hydrazidoyl sulfides, thiadiazolines and thiazole derivatives.The structures of these products were confirmed by elemental analyses and spectral data and wherever possible, alternate synthesis.Key words: Hydrazidoyl sulfides, thiadiazolines; thiazoles; coumarines; hydrazidoyl halides; N-phenylcyanothiacetamide.
