Abstract
An efficient protocol for chromium(III)-catalyzed C(sp2)–C(sp3) cross-coupling is reported. The alkylations of halo-quinoline and phenacyl derivatives proceed at room temperature within minutes using the tetrahydrofuran-soluble chromium(III) complex CrCl3·3THF. The reactions occur without the formation of homo-coupling side products, which are common for the related iron-, cobalt- or manganese-catalyzed cross-coupling reactions.
