dc.description.abstract3-Trifluoromethyl-7H-6(6 or 8, or 6,8-disubstituted-3-coumarino)-s-triazolo [3,4-b][1 ,3,4] thiadiazines 3 have been prepared from simple condensation of appropriate 3-trifluoromethyl-4-amino-5-mercapto-1,2,4-triazole 2 with various 3(2-bromoacetyl)coumarins in anhyd. ethanol and dimethyl formamide. Some 3-(2-phenyl hydrazino-4-thiazolyl) courmarins 5 have also been prepared by the condensation of 3-(2-bromoacetyl) coumarins 1 and N4-phenyl thiosemicarbazide 4 in anhyd. ethanol and dimethyl formamide. en_US
