  镍催化的CO 2对烯炔的还原性环化异构化

  摘要：

  羧酸根基团在生物活性分子中无处不在。由石油原料合成羧酸盐需要一系列氧化反应。CO 2代表了廉价且可持续的预氧化C1源。在这里，我们描述了一种简单，选择性和温和的方法，用于从1,6-和1,7-烯键和CO 2构造（杂）环α，β-不饱和羧酸。末端1,7-烯炔和位阻链烯烃的区域选择性发生变化，并形成未共轭的羧酸。还原环化的机理研究提出了一种氢化物插入途径，解释了空间效应引起的区域选择性的变化，并将这项工作与以前涉及CO 2的反应区分开来。

  Several diorganoscandium complexes stabilized by the beta -diketiminato ligands (Ar)NC(R)CHC(R)N(Ar) (Ar = 2,6-iPr-C6H3; R = CH3 (ligand a), R = rBu (ligand b)) have been synthesized. Reaction of the lithium salts of the ligands with ScCl3. 3THF leads to the complexes LScCl2(THF)(n), which may be readily alkylated to form the dialkyl derivatives. Most are isolated as base-free, four-coordinate complexes. Several have been characterized via X-ray crystallography, and a detailed discussion of their structures is presented. Steric interactions between Ar and the Sc-alkyl groups force the scandium to adopt an out-of-plane bonding mode. In solution, this is manifested via a fluxional process which equilibrates the two diastereotopic alkyl groups and ligand groups as well. The barriers to this process roughly correlate with the steric bulk of the alkyl substituents. At elevated temperatures, the dialkyl derivatives LScR2 undergo a metalation process whereby one of the alkyl groups is eliminated as RH, and a ligand iPr group is metalated in the methyl position. These reactions are first order in scandium complex, and activation parameters of DeltaH(double dagger) = 19.7(6) kcal mol(-1) and DeltaS(double dagger) = -17(2) cal mol(-1) K-1 were measured for the loss of Me4Si from (Ligb)Sc(CH2SiMe3)(2).
