Catalytic Direct Arylation of Heteroaromatic Compounds

Abstract The direct intermolecular arylation reactions of heteroaromatic compounds such as pyrroles, furans, thiophenes, azoles, and pyridines with aryl halides using palladium or rhodium catalysts have significantly been developed as effective, straightforward methods for making aryl–heteroaryl linkages, which are often found in biologically active compounds and π-conjugated functional materials. In this article is summarized the recent progress in this field.
