The synthesized compounds were tested in Suzuki-Miyaura cross-coupling (for 1-8) and arylation (for 5-8) reactions. As catalysts, they demonstrated a highly efficient route for the formation of asymmetric biaryl compounds even though they were used in very low loading. For example, all compounds displayed good catalytic activity for the C-C bond formation of 4-tert-butylphenylboronic acid with 4-chlorotoluene.eninfo:eu-repo/semantics/openAccessarylationbenzimidazolium saltscatalysisN-heterocyclic carbenePEPPSI complexSuzuki-Miyaura cross-coupling reactionN-Methylphthalimide-substituted benzimidazolium salts and PEPPSI Pd-NHC complexes: synthesis, characterization and catalytic activity in carbon-carbon bond-forming reactionsArticle1281882687781010.3762/bjoc.12.92-s2.0-84962261256Q2WOS:000368063800001Q2
