Abstract N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)cyanothioformamide was synthesized from the corresponding 4-amino-pyrazole. Various cyanothioformamides were reacted with different arylidenes of cyanothioacetamide to produce either 4-imino-5-thioxo-3-(pyrroline & pyrrolidine)carbonitrile or pyrrolo[3,2-d]thiazole. Interaction of thiohydantoin with the arylidenes of either malononitrile
