Abstract

A combination of site-selective N,N-di-Boc-activation of the amide nitrogen with practical air- and moisture-stable, well-defined, and highly reactive [Pd(NHC)(cin)Cl] enables a general, highly selective method for the room temperature Suzuki-Miyaura cross-coupling to provide biaryl ketones in high yields.
