Abstract

Palladium–benzimidazolium salt catalyst systems have been studied for the Suzuki coupling. A different substitutent effect has been uncovered with respect to nitrogen substituents in the benzimidazolium salts from the palladium–imidazolium salt analogs. A practical and highly active palladium catalyst system, PdCl2/N, N′- dibenzylbenzimidazolium chloride, has been identified for the Suzuki coupling of aromatic ...
