摘要：

The application of the reagent (Ipc)BCl2 (Ipc = isopinocampheyl) in the synthesis of a new tris(pyrazolyl)borate ligand having an Ipc substituent on boron is described. The sodium salt is a convenient precursor for the preparation of the complexes {(Ipc)tris(pyrazolyl)borato}tricarbonylmanganese and [{lpc)tris(pyrazolyl)borato}(p-cymene)-ruthenium](+), whose X-ray crystal structures are reported. While little distortion of the B(pz)(3)M unit is observed in these complexes, steric interaction between the Ipc group and the 3-positions of the pyrazolyl rings is noted to lead to distortion of the angles around the B-C bond.
