Abstract Hydrazonoyl chlorides 1 reacted with 2-aryl-1-cyano-1-thiazol-2-ylethenes 2 in presence of triethyl-amine to give the cycloadducts 4. which were converted to the corresponding pyrazoles 5 by the action of sodium methoxide. The reaction of hydrazonoylhalides 1 and 6 with each of 2-aryli-dene-2-cyanoethanethioamides 7 and 2-arylhydrazono-2-cyanoethanethioamides 14 in ethanolic tri-ethylamine
