Transition-metal-free C–H oxidative activation: persulfate-promoted selective benzylic mono- and difluorination

Author affiliations

Abstract

An operationally simple and selective method for the direct conversion of benzylic C–H to C–F to obtain mono- and difluoromethylated arenes using Selectfluor™ as a fluorine source is developed. Persulfate can be used to selectively activate benzylic hydrogen atoms toward C–F bond formation without the aid of transition metal catalysts.
