A nickel-catalyzed asymmetric C(sp2)−P cross-coupling for the synthesis of P-stereogenic phosphine oxides under mild conditions is reported. The enantioselective alkenylation/arylation of racemic secondary phosphine oxides with alkenyl/aryl bromides provided P-stereogenic phosphine oxides with high enantioselectivities of up to 99 % ee.
