  铱催化 1,1-二烷基乙烯与乙醇的对映选择性转移氢化：范围和机制

  摘要：

  尽管过渡金属催化的不对称烯烃氢化领域取得了半个世纪的进步，但纯烷基取代的1,1-二烷基乙烯的对映选择性氢化仍然是一个未解决的挑战。在此，我们描述了一种手性 PCN Ox -钳铱络合物，用于用乙醇对此类烯烃进行不对称转移氢化，提供全烷基取代的叔立体中心。在底物与仲/伯和伯/伯烷基组合的反应中可以实现高水平的对映选择性。该催化剂进一步应用于二取代烯醇的氧化还原异构化，产生远离所得羰基的叔立体中心。机理研究揭示了二氢化物 (PCN Ox )Ir(H) 2作为催化活性中间体，可以衰变成二聚体 (κ 3 -PCN Ox )IrH(μ-H) 2 IrH(κ 2 -PCN) Ox ) 通过配体重金属化途径。 H 2加氢条件下的催化剂失活比EtOH转移加氢条件下的催化剂失活快得多，这解释了为什么(PCN Ox )Ir催化剂对转移加氢有效但对加氢无效。通过区域选择性 1,2-插入抑制二取代到三取代的烯烃异构

  A convergent method for the stereoselective synthesis of trisubstituted alkenes

  摘要：

  A method for the stereoselective, convergent synthesis of trisubstituted alkenes has been developed. The procedure features the synthesis of allylic alcohols 9 by coupling an aldehyde with a vinyl organometallic reagent. Treatment of 9 with carbon disulfide and methyl iodide gave the intermediate allylic xanthates 10 that underwent facile [3,3]-sigmatropic rearrangement to give the dithiocarbonates 11 and 12, radical reduction of which gave the (E)-alkenes 13 as the major products.

  Nickel-catalyzed intermolecular benzylation and heterobenzylation of unactivated alkenes to provide functionalized allylbenzene derivatives are described. A wide range of both the benzyl chloride and alkene coupling partners are tolerated. In contrast to analogous palladium-catalyzed variants of this process, all reactions described herein employ electronically unbiased aliphatic olefins (including

  Thiourea–I2 as Lewis base–Lewis acid cooperative catalysts are developed for the iodochlorination of alkenes with in situ-generated iodine monochloride (I–Cl). The Lewis base–Lewis acid cooperative system is sufficient to generate I–Cl from I2 with a chlorinating reagent at low temperature. Based on the solid-state structure of the active species, thiourea–I2 cooperatively captures I–Cl. By taking

• Simplifying Nickel(0) Catalysis: An Air-Stable Nickel Precatalyst for the Internally Selective Benzylation of Terminal Alkenes
  作者：Eric A. Standley、Timothy F. Jamison

  DOI：10.1021/ja3116718

  日期：2013.1.30

  The synthesis and characterization of the air-stable nickel(II) complex trans-(PCy2Ph)(2)Ni(o-tolyl)Cl is described in conjunction with an investigation of its use for the Mizoroki-Heck-type, room temperature, internally selective coupling of substituted benzyl chlorides with terminal alkenes. This reaction, which employs a terminal alkene as an alkenylmetal equivalent, provides rapid, convergent access to substituted allylbenzene derivatives in high yield and with regioselectivity greater than 95:5 in nearly all cases. The reaction is operationally simple, can be carried out on the benchtop with no purification or degassing of solvents or reagents, and requires no exclusion of air or water during setup. Synthesis of the precatalyst is accomplished through a straightforward procedure that employs inexpensive, commercially available reagents, requires no purification steps, and proceeds in high yield.
