Mono(formazanate) boron difluoride complexes (LBF2), which show remarkably facile and reversible ligand-based redox-chemistry, were synthesized by transmetallation of bis(formazanate) zinc complexes with boron trifluoride. The one-electron reduction product LBF2Cp2Co and a key intermediate for the transmetallation reaction, the six-coordinate zinc complex (L(BF3))2Zn were isolated and fully characterized.
单（甲臜酸酯）二氟化硼配合物（LBF₂）通过双（甲臜酸酯）锌配合物与三氟化硼的金属转移反应合成，该配合物显示出非常容易且可逆的基于配体的氧化还原化学性质。分离并完全表征了单电子还原产物[LBF₂]⁻[Cp₂Co]⁺以及金属转移反应的关键中间体——六配位锌配合物（L(BF₃)）₂Zn。
