The palladium-catalysed direct arylation of heteroaromatics with unprotected iodoanilines
proceeds in moderate to high yields using only 1 mol% Pd(OAc)2 as the catalyst and potassium acetate as the base. No amination reaction was observed
under these conditions. A wide variety of heteroarenes have been successfully employed.
Key words
catalysis - amines - heterocycles - palladium - green chemistry
