  新的CNN型钌夹NHC复合物。酯的轻度，高效催化加氢

  摘要：

  新钳形钌络合物（2 - 6）基于新的联吡啶配体的NHC 1制备和研究，导致酯在温和的条件下相应的醇的有效催化氢化。配体1与RuH（Cl）CO（PPh 3）3反应，然后与一当量的碱KHMDS反应，得到混合了膦-NHC配合物2，并掺有C-H活化的联吡啶配体。复杂2具有含有两个磷原子的八面体结构的反式彼此，氢化物的反式的NHC配体和CO反联吡啶配体的C–H活化碳。使用前体络合物Ru（p- cymene）Cl 2（CO），与1反应，然后用一当量的KHMDS处理中间产物，导致形成平衡的二氯化物钳形络合物3a和3b，如所示通过可变温度的1 H NMR。络合物3a是八面体，中性和对称的络合物，如单晶X射线衍射所示，CO配体反式定位于钳位配体的中心吡啶基，而两个氯化物彼此反式定位。复合体3b是阳离子的，带有外层氯化物。所述NHC的反应配体1在低温下用随后加入期RuH（CL）的CO（PPH的LiHMDS 3）3，导致在混合膦-

  Allenamide Hydro−Hydroxyalkylation: 1,2-Amino Alcohols via Ruthenium-Catalyzed Carbonyl anti-Aminoallylation

  摘要：

  Exposure of alcohols to allenamides in the presence of RuHCl(CO)(PPh(3))(3) and dippf [dippf = bis(diisopropylphosphino)ferrocene] results in hydrogen transfer to generate aldehyde-allylruthenium pairs, which engage in C-C coupling to form products of carbonyl aminoallylation as single anti-diastereomers.

  Treatment of the chloro bridged dimer [(eta(6)-cymene)RuCl](2)(mu-Cl)(2)} (1) with the donor molecules P(OPh)(3), P(OMe)(3), PPh3, PMe3, CO, SMe2, (CNBu)-Bu-t and CNTos in hot hexane causes bridge splitting reactions that produce the monomeric compounds [(eta(6)-cymene)Ru(L)Cl-2], (4)-(11), respectively. Use of the chiral isonitrile S(-)-alpha-methylbenzylisonitrile produced the corresponding complex 12. The diiodo analogues, 13-15, were prepared similarly from [(eta(6)-cymene)RuI](2)(mu-I)(2)} (3) for P(OPh)(3), P(OMe)(3) and PPh3, respectively. Insertion of tin(II) chloride into both metal-chlorine bonds was observed for [(eta(6)-cymene)Ru(POMe}(3))Cl-2] (5), while only monosubstitution was observed for [(eta(6)-cymene)Ru(PPh3)Cl-2] (6). Halide abstraction in the presence of a substrate reaction has been used to prepare some selected cationic compounds which contain an asymmetric ligand environment. Reaction of [(eta(6)-cymene)RuCl](2)(mu-Cl)(2)} with 1,2-bis(diphenylphosphino)-ethane under ionising conditions produced the cation [(eta(6)-cymene)Ru(dppe)Cl]PF6 (20). Selected compounds have been examined by C-13-H-1} heteronuclear correlation and H-1-H-1} COSY and NOESY experiments. The structure of [(eta(6)-cymene)Ru(POPh}(3))Cl-2](CH2Cl2)-C-.
