Abstract
A mild and general protocol for the carbonylative Suzuki-Miyaura cross-coupling of sterically hindered ortho-disubstituted aryl iodides with various aryl boronic acids provides an array of substituted biaryl ketones in good yield. A carbonylative Negishi coupling that utilizes alkynyl nucleophiles is also described.
