Abstract
A mild coupling reaction catalyzed by Ni(acac)2-L4 has been studied. The catalyst acts efficiently in the reaction of biaryl coupling between various electrophiles and common or functionalized aryl Grignard reagents with high functional group tolerance. The study demonstrates that LiCl acts as an essential component in efficient cross-coupling by accelerating reduction of Ni(II) to Ni(0). The new catalytic system for selective couplings of aryl tosylates with aryl chlorides has been developed.
