Tunable C–H arylation and acylation of azoles with carboxylic acids by Pd/Cu cooperative catalysis

Abstract

Direct C–H arylation and acylation of azoles with carboxylic acids are achieved selectively through Pd/Cu cooperative catalysis: biaryls are generated selectively with dppp as ligand, while biaryl ketones are obtained with high selectivity using dpph or Ph₂PCy as ligand.
