  Syntheses of Mono- and Dinuclear Diiodoboryl Complexes of Platinum

  摘要：

  Treatment of [Pt(PCy3)(2)] (Cy = cyclohexyl) with Bl(3) afforded trans-[(Cy3P)(2)Pt(I)(Bl(2))] by the oxidative addition of a B-I bond. The title compound represents the first diiodoboryl complex and was fully characterized by NMR spectroscopy and X-ray diffraction analysis. The latter revealed a very short Pt-B distance, thus indicating a pronounced 7 contribution to this bond. By the addition of another 1 equiv of Bl(3) to, trans-[(Cy3P)(2)Pt(I) (BI2)], a new Pt species [(Cy3P)(I2B)Pt(mu-I)](2) was formed with concomitant buildup of the phosphine borane adduct [Cy3P-BI3]. The former is obviously obtained by abstraction of PCy3 from trans-[(Cy3P)(2)Pt(I)(BI2)] and the subsequent dimerization of two remaining fragments. Interestingly, the dimerization is reversible, and the dinuclear compound can be converted to trans-[(Cy3P)(2)Pt(I)(BI2)] upon the addition of PCy3.

  of tetraiododiborane (B2I4) with trans‐[Pt(BI2)I(PCy3)2] gives rise to the diplatinum(II) complex [(Cy3P)(I2B)Pt}2(μ2:η3:η3‐B2I4)], which is supported by a bridging diboranyl dianion ligand [B2I4]2−. This complex is the first transition‐metal complex of a diboranyl dianion, as well as the first example of intact coordination of a B2X4 (X=halide) unit of any type to a metal center.
