Abstract

The selectivity challenge associated with cross-coupling of aryl chlorides as inert electrophiles with aryl triflates as reactive ones is overcome using a multimetallic strategy with the appropriate choice of additive. LiCl is essential for effective cross-coupling by accelerating the reduction of Ni(II) to Ni(0) and counteracting autoinhibition of reduction at Zn(0) by Zn(II) salts.
