Benzimidazolium salts were used for synthesis of the PEPPSI (pyridine enhanced precatalyst preparation stabilization and initiation)-themed, six new Pd-complexes with the general formula [PdX2(NHC)(pyridine)]. The structures of all compounds were characterized by various spectroscopic techniques such as H-1 NMR, C-13 NMR and FT-IR. The more detailed structural characterization of four of the complexes was determined by single-crystal X-ray diffraction study. The catalytic activities of all Pd-complexes were evaluated in the direct arylation of the 2-acetylfuran and 2-acetylthiophene with aryl bromides in the presence of 1 mol% catalyst loading.eninfo:eu-repo/semantics/closedAccessdirect arylationheteroareneN-heterocyclic carbenepalladiumPEPPSIArticle34210.1002/aoc.53872-s2.0-85076105596Q2WOS:000500379900001Q1
