  Insertion of B−X (X = Cl, SMe₂) Moieties into Ruthenaborane Frameworks:  Synthesis and Characterization of (η⁵-C₅Me₅Ru)₂(μ-H)B₄H_mCl_n, (m, n = 4, 3; 5, 2; 7, 2), closo-1-(SMe₂)-2,3-(η⁵-C₅Me₅Ru)₂(μ₃-H)B₅HCl₃, and closo-2,3-(η⁵-C₅Me₅Ru)₂B₆H₃Cl₃

  摘要：

  The reaction of nido-1,2-(eta(5)-C5Me5Ru)(2)(mu-H)(2)B3H7 (1) with the dichloroborane BHCl2 center dot SMe2 results in the formation of three sets of B-Cl inserted metallaborane products: nido-1,2(eta(5)-C5Me5Ru)(2)(mu-H)B4H7Cl2 (2), pileo-2,3-(eta(5)-C5Me5Ru)(2)(mu-H)B4H5Cl2 (three geometric isomers, 3-5), and pileo-2,3-(eta(5)-C5Me5Ru)(2)(mu-H)B4H4Cl3 (a pair of geometric isomers, 6 and 7). When the same reaction was carried out under more forcing conditions, three new metallaborane compounds, closo-1-(SMe2)-2,3-(eta(5)-C5Me5Ru)(2)(mu(3)-H)B5HCl3 (a pair of geometric isomers, 8 and 9) and closo-2,3-(eta(5)-C5Me5Ru)(2)B6H3Cl3 (10), were isolated in low yield in addition to 2-7. Compounds 8 and 9 exhibit a capped-octahedral geometry, and 10 exhibits a seven-sep (skeletal electron pair) bicapped-octahedral geometry. Reaction of nido-2,4-(eta(5)-C5Me5Ru)(2)B6H12 and nido-2,3-(eta(5)-C5Me5Ru)(2)B8H12 with BHCl2 center dot SMe2 results in substitution of terminal H by Cl, producing nido-2,4-(eta(5)-C5Me5Ru)(2)B6H10Cl2 (11) and nido-2,3-(eta(5)-C5Me5Ru)(2)B8H11Cl (12) in 82% and 75% yields, respectively.
