    摘要:
    试图通过用约3-6的处理来诱导膦-Gallane加合物Cy2PH.GaH3(Cy = cyclohexyl)(1)的催化脱氢偶联。5 mol%的Rh(I)络合物[{Rh(mu-Cl)(1,5-cod)} 2](cod =环辛二烯)或Rh(0)物种Rh / Al2O3和[Oct4N] Cl-稳定的胶体Rh导致催化的P-Ga键断裂,生成膦,H2和Ga金属。有趣的是,随后用Me 2 NH.BH 3处理反应混合物未能通过Rh催化的脱氢偶联形成[Me 2 N-BH 2] 2,这表明发生了催化剂失活。涉及用Cy2PH,PMe3或GaH3.OEt2处理活性Rh(0)催化剂的中毒研究表明,由于Me2NH.BH3的脱氢偶联速率显着降低或根本没有发生,因此确实发生了失活。经Cy2PH和PMe3处理的胶体Rh(0)的X射线光电子能谱分析证实,在每种情况下,催化剂表面均存在磷,这与通过膦连接而引起的催化剂中毒相一致。提出了1和Me3P

  • Poisoning of Heterogeneous, Late Transition Metal Dehydrocoupling Catalysts by Boranes and Other Group 13 Hydrides

    Borane reagents are widely used as reductants for the generation of colloidal metals. When treated with a variety of heterogeneous catalysts such as colloidal Rh, Rh/Al2O3, and Rh(0) black, BH3 center dot THF (THF = tetrahydrofuran) was found to generate H-2 gas with the concomitant formation of a passivating boron layer on the surface of the Rh metal, thereby acting as a poison and rendering the catalyst inactive toward the dehydrocoupling of Me2NH center dot BH3. Analogous poisoning effects were also detected for (i) colloidal Rh treated with other species containing B-H bonds such as [HB-NH](3), or Ga-H bonds such as those present in GaH3 center dot OEt2, (ii) colloidal Rh that was generated from Rh(I) and Rh(III) salts using borane or borohydrides as reductants, and (iii) for other metals such as Ru and Pd. In contrast, analogous poisoning effects were not detected for the catalytic hydrogenation of cyclohexene using Rh/Al2O3 or the Pd-catalyzed Suzuki cross-coupling of PhB(OH)(2) and PhI. These results suggest that although this poisoning behavior is not a universal phenomenon, the observation that such boron layers are formed and surface passivation may exist needs to be carefully considered when borane reagents are used for the generation of metal colloids for catalytic or materials science applications.
