Reactivity of N-1-tosylamidrazones with thionyl chloride and Lawesson reagent: Preparation of thiatriazoles and triazaphospholines [French]

摘要

Thionyl chloride 2 and Lawesson Reagent (L.R.) 4 react with N-1-tosylamidrazones 1 to give respectively 1-oxyde-1,2,3,5-thiatriazole 3 and triazaphospholines 5 derivatives. The structure of products 3 and 5 is confirmed by IR and NMR spectroscopy. [References: 12]
