  用于硅烷还原酰胺的BEt 3基催化剂

  摘要：

  本文报道了一种简单但实用的催化体系的开发，该体系用于用氢硅烷或氢硅氧烷选择性还原酰胺。发现低成本且易于获得的三乙基硼烷（在THF中为1.0 M）与催化量的碱金属碱结合，可催化所有三种酰胺类别（叔，仲和伯酰胺）的还原反应，从而在室温下形成胺。温和的条件。另外，还可以通过使用BEt 3和碱的适当组合来实现将仲酰胺选择性转化为醛亚胺和将伯酰胺选择性转化为腈。这些赌注3的范围碱催化的酰胺氢化硅烷化反应已被深入研究。机理研究的初步结果表明，经过改进的Piers硅烷Si–H···B活化方式，其中BEt 3提取氢化物的过程是通过烷氧基或氢氧根阴离子与Si中心的配位来促进的。

  modular aerobic oxidation of amines to imines has been achieved using an ortho-naphthoquinone (o-NQ) catalyst. The cooperative catalyst system of o-NQ and Cu(OAc)2 enabled the formation of homocoupled imines from benzylamines, while the presence of TFA helped the formation of cross-coupled imines in excellent yields. The current mild aerobic oxidation protocol could also be applied to the oxidation of secondary

  使用邻萘醌（o- NQ）催化剂已经实现了将胺进行模块化好氧氧化成亚胺的方法。o -NQ和Cu（OAc）2的协同催化剂体系能够由苄胺形成均偶联的亚胺，而TFA的存在有助于以优异的产率形成交叉偶联的亚胺。当前的温和的好氧氧化方案也可以在助催化剂Ag 2 CO 3的帮助下，将仲胺氧化为亚胺或酮亚胺，收率很好。
