Reaction of Trifluoronitrosomethane with Arenesulfonohydrazides. Synthesis of N-Trifluoromethyl-N-hydroxyarenesulfonamides
The reaction of trifluoronitrosomethane 1 with arenesulfonohydrazides resulted in the formation of N-trifluoromethyl-N-hydroxyarenesulfonamides 3 which were characterized by spectral and elemental analyses.It showed a sharp contrast to the reaction of 1 with acyl- or carbamoylhydrazines, which afforded the corresponding trifluoromethylazo compounds.As an alternative route, 3 could be synthesized by the reaction of 1 with arenesulfinic acids or their salts.The sulfonamides 3 were converted to the corresponding methyl ethers or tosylates.
