Article abstract of DOI:10.1021/acs.inorgchem.5b00929

The zinc adduct {[HB(3,5-(CF3)2Pz)3]Zn}+, which was generated from [HB(3,5-(CF3)2Pz)3]ZnEt and [Ph3C]{B[3,5-(CF3)2C6H3]4}, catalyzes the activation of C-halogen bonds of chloromethanes via carbene insertion. Ethyl diazoacetate serves as the carbene precursor. The presence of {[HB(3,5-(CF3)2Pz)3]Zn}+ in the reaction mixture was confirmed by obtaining {[HB(3,5-(CF3)2Pz)3]Zn(CNtBu)3}+ using CNtBu as a trapping agent. {[HB(3,5-(CF3)2Pz)3]Zn(CNtBu)3}+ loses one zinc-bound CNtBu easily to produce five-coordinate {[HB(3,5-(CF3)2Pz)3]Zn(CNtBu)2}+.
