H2S04 with constant stirring in cold and 5-substituted aryl-2-substituted arylamino-1 ,3,4-thiadiazolo[3,2-c]thiazoles have been synthesised by the cyclisation of 2- substituted aryl-3-substituted arylthiourido-thiazolidin-4-ones with conc. H2S04 with constant stirring in cold and screened for their antifungal activities against Helminthosporium oryzae and Cephalosporium sacchari.
