Using TMPZnCl center dot"LiCl as a kinetically highly active base, nitriles and esters undergo a Pd-catalyzed alpha-arylation under mild conditions. Remarkably, in the case of alpha,beta or beta,gamma-unsaturated nitriles, a regioselective gamma-arylation or a gamma-alkenylation is observed.

challenging but synthetically indispensable approach to α-branched carbonyl motifs that are widely represented among drugs, natural products, and synthetic intermediates. Here, we describe a simple approach to generation of boron enolates in the absence of strong bases that allows for introduction of both α-alkyl and α-aryl groups in a reaction of readily accessible 1,2-dicarbonyls and organoboranes.
