摘要

Abstract N-Phenyltrifluoroacetohydrazonoyl bromide (1) reacted with potassium isothiocyanate and isocyanate to give 5-imino-4-phenyl-2-trifluoromethyl-δ 2-1, 3, 4- thiadiazoline and 1-phenyl-3-trifluoromethyl-δ 2-1, 2, 4-triazolin-5-one, respectively. On treatment with several types of cumulative double bonds such as alkyl isothiocyanate, isocyanate, and carbodiimide, 1 afforded regioselectively the corresponding ...
