  Co-catalyzed autoxidation of alkene in the presence of silane. The effect of the structure of silanes on the efficiency of the reaction and on the product distribution

  摘要：

  A systematic investigation of the structural effect of silanes on the Co-catalyzed reductive oxygenation of alkene in the presence of silane (Mukaiyama-Isayama reaction) showed that the efficiency of the reaction decreases with the increase of the steric bulk of the silanes. A similar trend was observed for the metal-exchange reaction between Co(III)-alkylperoxo complex and silane, too. The peroxidation of (S)-limonene, followed by deprotection of the derived silyl peroxides, provides a mixture of the corresponding monocyclic hydroperoxide 24 and the bicyclic one 25, the ratio being a marked function of the steric bulk of silanes.

  Intermolecular Antiselective and Enantioselective Reductive Coupling of Enones and Aromatic Aldehydes with Chiral Rh(Phebox) Catalysts

  摘要：

  The intermolecular reductive coupling reaction of cyclopent-2-enone and aromatic aldehydes was realized by chiral rhodium-(bisoxazolinyl)phenyl catalysts, Rh(Phebox-Ph)(OAc)(2)(H2O), with diphenymethylsilane as a hydride donor to give the corresponding beta-hydroxyketones in high anti selectivity (up to 96%) with high enantioselectivity (up to 93%).

• <i>N</i>-Methyl-Benzothiazolium Salts as Carbon Lewis Acids for Si−H σ-Bond Activation and Catalytic (De)hydrosilylation
  作者：Valerio Fasano、James E. Radcliffe、Liam D. Curless、Michael J. Ingleson

  DOI：10.1002/chem.201604613

  日期：2017.1.1

  N−Me‐Benzothiazolium salts are introduced as a new family of Lewis acids able to activate Si−H σ bonds. These carbon‐centred Lewis acids were demonstrated to have comparable Lewis acidity towards hydride as found for the triarylboranes widely used in Si−H σ‐bond activation. However, they display low Lewis acidity towards hard Lewis bases such as Et3PO and H2O in contrast to triarylboranes. The N−Me‐benzothiazolium

  N -Me-苯并噻唑鎓盐是一种新的路易斯酸家族，能够激活 Si-H σ 键。这些以碳为中心的路易斯酸被证明对氢化物具有与广泛用于 Si−H σ 键活化的三芳基硼烷相当的路易斯酸性。然而，与三芳基硼烷相比，它们对硬路易斯碱（例如Et 3 PO和H 2 O）表现出低路易斯酸性。N - Me-苯并噻唑鎓盐是一系列氢化硅烷化和脱氢硅烷化反应的有效催化剂。明智地选择这些阳离子中的 C2 芳基取代基可以调节亲电中心周围的空间和电子环境，从而产生更具活性的催化剂。最后，相关的苯并恶唑鎓盐和苯并咪唑鎓盐也被发现对 Si−H 键活化具有活性，并可作为亚胺氢化硅烷化的催化剂。

  enantioselection usually depends on differences in steric interactions between prochiral substrates and a chiral catalyst. We have discovered a carbene Si-H insertion in which the enantioselectivity depends primarily on the electronic characteristics of the carbene substrate, and the log(er) values are linearly related to Hammett parameters. A new class of chiral tetraphosphate dirhodium catalysts was developed

  催化对映选择通常取决于前手性底物和手性催化剂之间空间相互作用的差异。我们发现了一种卡宾 Si-H 插入，其中对映选择性主要取决于卡宾底物的电子特性，并且 log(er) 值与哈米特参数线性相关。开发了一类新的手性四磷酸二铑催化剂，该催化剂在二芳基卡宾插入硅烷的 Si-H 键方面表现出优异的活性和对映选择性。计算和机械研究表明卡宾的两个芳基之间的电子差异如何导致非对映过渡态能量的差异。该研究为利用基材的电子特性进行不对称催化提供了一种新策略。

  The first iron‐catalyzed 1,2‐difunctionalization of styrenes and conjugated alkenes with silanes and either N or C, using an oxidative radical strategy, is described. Employing FeCl2 and di‐tert‐butyl peroxide allows divergent alkene 1,2‐difunctionalizations, including 1,2‐aminosilylation, 1,2‐arylsilylation, and 1,2‐alkylsilylation, which rely on a wide range of nucleophiles, namely, amines, amides
