All of the complexes were characterized using elemental analysis, H-1 NMR and C-13 NMR spectroscopy. The catalytic activity of Pd(II)-NHC complexes in the direct arylation of pyrrole derivatives was investigated. These Pd(II)-NHC complexes showed the good catalytic performance for the direct arylation of pyrrole derivatives with readily available and inexpensive aryl chlorides. The arylation reactions regioselectively produced C2- or C5-arylation products in moderate to good yields by using 1 mol% of the palladium complex. (C) 2017 Elsevier B.V.
