摘要：

Dimethylaluminum or ethylzinc complexes of highly fluorinated tris(pyrazolyl) borate ligand [HB(3,5-(CF3)(2)PZ)(3)](-) can be obtained in excellent yield from the reaction between the silver adduct [HB(3,5-(CF3)(2)PZ)(3)]Ag(THF) and the metal alkyl reagent Me3Al or Et2Zn. The X-ray crystal structure of [HB(3,5-(CF3)(2)Pz)(3)]AlMe2 shows that the tris(pyrazolyl)borate ligand coordinates to the aluminum center in kappa(2)-fashion. [HB(3,5-(CF3)(2)Pz)(3)]ZnEt features the typical kappa(3)-bonded ligand.
