  摘要：

  我们报道了锰催化的各种伯酰胺向胺的加氢甲硅烷基化还原（25个例子）。通过简单地改变反应条件，例如在催化量的仲酰胺存在下，相同的催化剂就能以优异的收率将伯酰胺转化为中间体腈化合物（16个实例）。这是第一个实例，其中已经证明了用单一催化剂将伯酰胺控制地催化转化为胺或腈。

  potassium complex was used as a transition metal-free catalyst for reduction of primary amides to corresponding primary amines under ambient conditions. Only 2 mol% loading of the catalyst exhibits a broad substrate scope including aromatic, aliphatic and heterocyclic primary amides with excellent functional group tolerance. This method was applicable for reduction of chiral amides and utilized for the synthesis

  In recent years, the applications of low-valent main group compounds have gained momentum in the field of catalysis. Owing to the accessibility of two lone pairs of electrons, NHC-stabilised phosphinidenes have been found to be excellent Lewis bases; however, they cannot yet be used as catalysts. Herein, an NHC-stabilised phosphinidene, 1,3-dimethyl-2-(phenylphosphanylidene)-2,3-dihydro-1H imidazole

  近年来，低价主族化合物在催化领域的应用得到了蓬勃发展。由于两个孤对电子的可及性，已发现 NHC 稳定的膦亚基是极好的路易斯碱；然而，它们还不能用作催化剂。在此，报道了一种 NHC 稳定的膦亚基，1,3-二甲基-2-(苯基亚膦基)-2,3-二氢-1 H咪唑 (1)，用于活化 CO 2。对 CO 2活化的仔细检查通过 DFT 计算以及本征键轨道分析的过程表明，膦亚基通过两个苯环之间的非共价 π-π 相互作用与苯基硅烷相关联，这激活了 Si-H 键，促进了氢化物转移到 CO 2分子。详细的 DFT 研究与光谱实验相结合，以了解 CO 2活化的机制及其催化还原官能化，导致一系列化学惰性伯酰胺在温和反应条件下甲酰化。

  作者：Jagadish Das、Debasis Banerjee

  DOI：10.1021/acs.joc.7b03215

  日期：2018.3.16

  Herein, we developed an operational simple, practical, and selective Ni-catalyzed synthesis of secondary amides. Application of renewable alcohols, earth-abundant and nonprecious nickel catalyst facilitates the transformations, releasing water as byproduct. The catalytic system is tolerant to a variety of functional groups including nitrile, allylic ether, and alkene and could be extended to the synthesis
