Rh-catalyzed intramolecular sp2 C-H bond difluoromethylenation

Chem Commun (Camb). 2012 Mar 25;48(25):3136-8. doi: 10.1039/c2cc30207a. Epub 2012 Feb 13.

Abstract

A new Rh-catalyzed intramolecular coupling reaction of a CF(2)Br group with a 2-aryl of indole or pyrrole via C-H bond activation is presented. This reaction represents a new way of incorporating difluoromethylene groups into organic compounds. Preliminary mechanistic studies suggest that this reaction might not occur via a conventional free radical pathway.
