  Acceptorless, Neat, Ruthenium-Catalyzed Dehydrogenative Cyclization of Diols to Lactones

  摘要：

  We report the dehydrogenation of 1,4-butanediol to γ-butyrolactone catalyzed by soluble ruthenium complexes without solvent or a hydrogen acceptor. An alkylphosphine version of ruthenium bis-phosphine diamine catalysts has been prepared and was found to be the longest-lived catalyst for the conversion of 1,4-butanediol to γ-butyrolactone. The catalytic production of γ-butyrolactone from 1,4-butandiol with this catalyst is simple to conduct, environmentally friendly, and highly efficient.

  cis-[Ru(PMe3)4(H)2] (1) reacts by two distinct photochemical pathways resulting in the formation of [Ru(PMe3)4] and [Ru(PMe3)3(H)2]; derivatives of these intermediates are generated in the presence of CO and Ph2SiH2.

  cis-[Ru(PMe3)4(H)2] (1) 通过两条不同的光化学途径反应，生成 [Ru(PMe3)4] 和 [Ru(PMe3)3(H)2]；在 CO 和 Ph2SiH2 存在的情况下，会生成这些中间体的衍生物。

  studies reveal that complexes Ru(CO)(2)(H)(2)L(2) (L = PMe(3), PMe(2)Ph, and AsMe(2)Ph) can have three geometries, ccc, cct-L, and cct-CO, with equilibrium ratios that are highly dependent on the electronic properties of L; the cct-L form is favored, because the sigma-only hydride donor is located trans to CO rather than L. When L = PMe(3), the ccc form is only visible when p-H(2) is used to amplify its

  NMR研究显示，配合物Ru（CO）（2）（H）（2）L（2）（L = PMe（3），PMe（2）Ph和AsMe（2）Ph）可以具有三种几何形状，ccc， cct-L和cct-CO，其平衡比高度依赖于L的电子性质；cct-L形式是受青睐的，因为只有sigma的氢化物供体位于CO而非L处。当L = PMe（3）时，仅当使用pH（2）放大其光谱特征时ccc形式才可见。相反，当L = AsMe（2）Ph时，ccc和cct-L形式的含量相似，因此必须具有相似的自由能。但是，对于这种配合物，cct-CO异构体也是可检测的。这些复合体经历了许多动态过程。对于L（2）= dppe，ccc形式中氢化物位置的互换显示出伴随同步的CO交换和两个磷原子的互换。认为该过程涉及包含eta（2）-H（2）配体的三角双锥体过渡态的形成。鉴于k（HH）/ k（DD）为1.04且L（2）= dppe时同步旋转，该过渡状态必须
