Synthesis of NHC Complexes by Oxidative Addition of 2-Chloro-N-methylbenzimidazole

The oxidative addition of 2-chloro-N-methylbenzimdazole to complexes of type [M(PPh3)4] yields after N-protonation compounds with NH,NMe-substituted NHC ligands. For M = Pd complex compound trans-[3]BF4 was obtained, while the oxidative addition for M = Pt yielded a mixture of cis-[4]BF4 (major) and...
