文摘

The cationic zinc adduct {[HB(3,5-(CF₃)₂Pz)₃]Zn(NCMe)₂}ClO₄ catalyzes the functionalization of tertiary, secondary, and primary C鈥揌 bonds of alkanes via carbene insertion. Ethyl diazoacetate serves as the :CHCO₂Et carbene precursor. The counteranion, supporting ligand, and coordinating solvents affect the catalytic activity. An in situ generated {[HB(3,5-(CF₃)₂Pz)₃]Zn}⁺ species containing a bulkier {B[3,5-(CF₃)₂C₆H₃]₄}^{鈭?/sup> anion gives the best results among the zinc catalysts used.}
