2-氯-N-甲基苯并咪唑与NH，NME取代的NHC配体发生质子化反应后，与[M(PPh_3)(4)]型化合物发生氧化加成反应。对于M=Pd，生成了反式-[3]BF4络合物，而对于M=铂，氧化加成生成了顺式-[4]BF4(主要)和反式-[4]BF4(次要)的混合物。
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 trans-[4]BF4 (minor).
