Abstract

Abstract The carbonylative Suzuki cross-coupling reactions of boronic acids with aryl iodides catalyzed by Pd 2 (dba) 3 as a ligand-free catalyst under atmospheric pressure of carbon monoxide has been firstly developed. Under mild reaction conditions, a broad range of aryl/heteroaryl iodides and aryl/heteroaryl boronic acids were selectively coupled to afford the corresponding diaryl ketones in good to excellent yields at low catalyst loadings (0.05 ...
