Synthesis and characterization of 1-phenyl-3-alkylbenzimidazol-2-ylidene salts and their catalytic activities in the Heck and Suzuki cross-coupling reactions
The synthesis and characterization of 1-phenyl-3-alkyl-substituted carbene precursors that
were prepared from 1-phenyl substituted benzimidazole and various alkyl halides are
reported. The new benzimidazolium salts (1a–e) were characterized by 1H NMR, 13C NMR,
FT-IR spectroscopic methods and elemental analyses. New in situ generated palladium-
benzimidazolium complexes were tested for catalytic activity in the Mizoroki-Heck and
Suzuki-Miyaura cross-coupling reactions.
