New Alkyl Organo Complexes of Ruthenium:  X-ray Molecular Structure of a [Hydridotris(pyrazolyl)borato]methylruthenium Complex, [RuTp(CH3)(cod)] (Tp = Hydridotris(3,5-dimethylpyrazolyl)borate, cod = 1,5-Cyclooctadiene), Containing an Unusual Three-Center B(μ-H)Ru Bond

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 o...

Description
Summary: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(μ-H)Ru bond was found.
