Reactions of α-S-cyanothioketones 6a-c with malononitrile were observed to form 2-(thiazol- 2(3H)-ylidene)malononitrile derivatives 7a-c. The thiazole products readily react with aromatic diazonium salts to yield 2-(5-phenylazo-3H-thiazol-2-ylidene)-malononitrile derivatives 8a-c. The malononitrile derivative 8c undergoes a condensation with DMF/DMA to yield thiazolo(5,4- c)pyridazine 12. Reactions
