  Access to Ruthenium(0) Carbonyl Complexes via Dehydrogenation of a Tricyclopentylphosphine Ligand and Decarbonylation of Alcohols

  摘要：

  The carbonylruthenium(0) complex Ru(CO){PCyp(2)(eta(2)-C5H7)}(2) (4) has been prepared by reaction of RuH2 {PCyp(2)(eta(2)-C5H7)}(2) (3) with an excess of tert-butylethylene in the presence of ethanol. Decarbonylation of ethanol is also observed when reacting the bis(dihydrogen) complex RuH2(eta(2)-H-2)(2)(PCyp(3))(2) (1) with 2 equiv of ethanol. The reaction results formally in the substitution of one dihydrogen ligand by a carbonyl, and the corresponding complex RuH2(eta(2) H-2)(CO)(PCyp(3))(2) (5) was isolated. An excess of tert-butylethylene reacted with 5 to give RuH2(CO) {PCyp(2)(eta(2)-C5H7)}(PCyp(3)) (6), which corresponds to the formal loss of 2 equiv of dihydrogen: loss of the dihydrogen ligand and dehydrogenation of one cyclopentyl ring. The dihydride 6 can be dehydrogenated further by reaction with ethylene, affording the ruthenium(0) complex Ru(eta(2)-C2H4)(CO){PCyp(2)(eta(2)-C5H7)}(PCyp(3)) (7). Finally, the dicarbonyl complex RuH2(CO)(2)(PCyp(3))(2) (8) was isolated by exposing I to 3 bar of CO. 8 and the new complexes 4-7, resulting from partial dehydrogenation of one or two cyclopentyl rings of the tricyclopentylphosphines and/or decarbonylation of alcohol, were characterized by multinuclear NMR, IR, elemental analysis, and X-ray diffraction.

  molecule, remains an elementary C1 building block to be observed. Herein we report the direct observation of free formaldehyde from the borane reduction of CO2 catalyzed by a polyhydride ruthenium complex. Guided by mechanistic studies, we disclose the selective trapping of formaldehyde by in situ condensation with a primary amine into the corresponding imine in very mild conditions. Subsequent hydrolysis

  CO2 的功能化是一个具有挑战性的目标，在温和条件下生成 HCOOH、CO、CH3OH 和 CH4 的先例存在。在这个系列中，CH2O 是一种非常活泼的分子，仍然是有待观察的基本 C1 构建块。在此，我们报告了由多氢化钌配合物催化的 硼烷还原反应中游离甲醛的直接观察。在机理研究的指导下，我们公开了通过在非常温和的条件下与伯胺原位缩合成相应的亚胺来选择性捕获甲醛。随后水解成胺和福尔马林溶液，首次证明 可用作生产甲醛的 C1 原料。
