  Highly Regioselective Carbonylation of Unactivated C(sp³)–H Bonds by Ruthenium Carbonyl

  摘要：

  The regioselective carbonylation of unactivated C(sp(3))-H bonds of aliphatic amides was achieved using Ru-3(CO)(12) as a catalyst. The presence of a 2-pyridinylmethylamine moiety in the amide is crucial for a successful reaction. The reaction shows a preference for C-H bonds of methyl groups as opposed to methylene C-H bonds and tolerates a variety of functional groups. The stoichiometric reaction of an amide with Ru-3(CO)(12) gave a dinuclear ruthenium complex in which the 2-pyridinylmethylamino moiety was coordinated to the ruthenium center in an N,N manner.

  The regioselective carbonylation of unactivated C(sp3)–H bonds of aliphatic amides, using 2-pyridinylmethylamine as a directing group in conjunction with Ru3(CO)12 as a catalyst is described. The presence of a 2-pyridinylmethylamine moiety in the amides is crucial for the success of the reaction. Although ethylene is not incorporated into the products, its presence is also essential for the reaction

  描述了使用2-吡啶基甲胺作为导向基团并结合Ru 3（CO）12作为催化剂，脂族酰胺未活化的C（sp 3）-H键的区域选择性羰基化。酰胺中2-吡啶基甲胺部分的存在对于反应的成功至关重要。尽管没有将乙烯掺入产物中，但是乙烯的存在对于进行反应也是必不可少的。此外，添加H 2O对于反应有效进行很重要。与亚甲基CH键相比，该反应显示出对甲基CH键的高度优先选择，即使亚甲基CH键也被氧原子或芳基激活。另外，该反应耐受各种官能团，例如MeO，Cl，CF 3，CN，甚至Br取代基。尽管使用α，α-二取代的脂族酰胺可以得到高的产率，但是α-单取代的脂族酰胺的反应可以以较低的产率得到相应的羰基化产物。在α-单取代的脂族酰胺中使用空间上需要的导向基团，例如1-（2-吡啶基乙基）胺部分，提高了产物的产率。酰胺与Ru 3的化学计量反应（CO）12得到稳定的二核钌配合物，为单个钌配合物，其中2-吡啶基甲基氨基部分与N
