High chemoselectivity to the construction of aryl methyl sulfones via an unexpected C-S bond formation between sulfonylhydrazides and dimethyl phosphite
Keyword(s):
In this research, a high chemoselectivity to access aryl methyl sulfones via an unexpected C-S bond formation between sulfonylhydrazides and dimethyl phosphite catalyzed by NaI under mild conditions was established. This transformation provides an alternative and metal-free path way to acquire various aryl methyl sulfones in good to excellent yields. Notably, dimethyl phosphite was employed as a type of stable and readily available alkyl source.
