摘要
Reaction of WO2Cl2 with K{HB(Me2pz)3} [HB-(Me2pz)3- = hydrotris(3,5-dimethyl-1-pyrazolyl)borate anion] in N,N-dimethylformamlde produces cis-{HB-(Me2pz)3}WO2Cl (1), which reacts with Grignard reagents in tetrahydrofuran to yield the organometallic dioxo-W(VI) complexes cis-{HB(Me2pz)3}WO2(R) (R = Me (2), Et (3), CH2Ph (4), Ph (5)). The X-ray structures of 3 and 5 reveal that the monomeric complexes possess distorted-octahedral coordination spheres composed of a facially tridentate HB(Me2pz)3- ligand, two terminal oxo ligands, and an eta-1-hydrocarbyl group.
