The structures of all isolated compounds were elucidated based on spectroscopic methods (H-1 and C-13 NMR, FT-IR and LC-MS spectroscopy). Under optimized reaction conditions, C5-arylated products were obtained in moderate to excellent yields in the direct arylation of heteroaromatics. (C) 2021 Elsevier B.V.
