Visible light-mediated C-H difluoromethylation of electron-rich heteroarenes

Org Lett. 2014 Jun 6;16(11):2958-61. doi: 10.1021/ol501094z. Epub 2014 May 9.

Abstract

A novel method for visible-light photoredox-catalyzed difluoromethylation of electron-rich N-, O-, and S-containingheteroarenes under mild reaction conditions is developed. Mechanistic investigation indicates that the net C-H difluoromethylation proceeds through an electrophilic radical-type pathway.
