文摘

NHC-Pd(II)-Im complex showed efficient catalytic activity toward the direct CH bond arylation of (benzo)thiophenes with the challenging aryl chlorides. Under the suitable conditions, all reactions proceeded smoothly to give the desired CH bond arylated products in acceptable to high yields, giving an inexpensive and alternative methodology for the arylation of (benzo)thiophenes.
