Abstract

A mild, copper-catalyzed cross-coupling of Ruppert-Prakash type reagents (TMSCF3, TMSC2F5, and TMSC3F7) with aryl and alkyl bromides provides a diverse array of trifluoromethyl, pentafluoroethyl, and heptafluoropropyl adducts. This light-mediated transformation enables also the late-stage functionalization of several drug analogues.
