Under the optimal conditions, these palladium(II)-NHC complexes showed the good catalytic performance for the direct C-H bond arylation of 2-substituted furans with (hetero)aryl bromides, and with readily available and inexpensive aryl chlorides. The C-H bond arylation regioselectively produced C5-arylated furans by using 1mol% of the palladium(II)-NHC catalysts in moderate to high yields.eninfo:eu-repo/semantics/closedAccessbenzimidazolium saltdirect C-H bond arylationfuranN-Heterocyclic carbenepalladiumArticle32710.1002/aoc.43992-s2.0-85046036779Q2WOS:000435929700025Q1
