  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.

  Investigation of the reactivity of the molybdenum borylene complex [(OC)5Mo=B=N(SiMe3)2] towards the late transition metal complexes [M(PCy3)2] (M = Pd, Pt) indicated the formation of [(OC)4Mo(μ-CO)μ-BN(SiMe3)2}Pd(PCy3)] and [(Cy3P)(OC)3Mo(μ-CO)μ-BN(SiMe3)2}Pt(PCy3)], respectively, as the first Mo-based semi-bridging borylene complexes. The new complexes were fully characterised spectroscopically and

  Several Pd(0) complexes catalyze the dimerization of Mes*PCNPh [2, Mes* = 2,4,6-(t-Bu)3C6H2] to the unsymmetrical heterocycle Mes*P(μ-CNPh)NPh(μ-CPMes*) (5). The symmetrical dimer [Mes*P(μ-CNPh)]2 (7), which forms slowly by uncatalyzed dimerization of 2, does not interconvert with 5; both 5 and 7 were structurally characterized by X-ray crystallography.

  Oxidative addition of B−halogen bonds to Pt(0) centers generally leads to corresponding trans-halo(boryl)complexes. Here, we report on a series of unprecedented cis-bromo(boryl)species of the type cis-[(dcpe)PtB(Br)R)(Br)], which were obtained from corresponding complexes trans-[(Cy3P)2PtB(Br)R}(Br)] (R = Fc, Pip, Mes) (Cy = cyclohexyl; Fc = ferroceny; Pip = piperidyl, Mes = mesityl) upon treatment
