摘要：
4-Substituted thiosemicarbazides react with di- and trifluoroacetic acids to give the corresponding 3-fluoroalkyl-4,5-dihydro-1,2,4-triazole-5(1H)-thiones. Condensation of 4,4-disubstituted thiosemicarbazides with trifluoroacetic acid leads to formation of 2-amino-5-trifluoromethyl-1,3,4-thiadiazoles.
