New alkyl organo complexes of ruthenium: X-ray molecular structure of a [hydridotris(pyrazolyl)borato]methylruthenium complex, [RuTp(CH3)(cod)] (Tp equals hydridotris(3,5-dimethylpyrazolyl)borate, cod equals 1,5-cyclooctadiene), containing an unusual three-center B(mu-H)Ru bond

摘要：

The reaction of [RuCl2(cod)(bpzm)] (1; cod = 1,5-cyclooctadiene, bpzm = bis(pyrazol-1-yl)methane) with MeMgCl gives [RuMeCl(cod)(bpzm)] (2). This complex reacts with AgCF3SO3, affording [RuMe(CF3SO3)(cod)(bpzm)] (3) and AgCl. [RuTpMe(cod)] (4) and [RuTp*Me(cod)] (5) were prepared from the reaction of 3 with KTp (Tp = hydridotris(pyrazolyl)borate) and KTp* (Tp* = hydridotris(3,5-dimethylpyrazolyl)borate), respectively. Compound 5 was characterized by X-ray diffraction. The molecule shows unusual coordination of the hydridotris(3,5-dimethylpyrazolyl)borate ligand, where a three-center B(mu-H)Ru bond was found.
