  Electronic Effects of Ring Substituents on Triplet Benzylic Biradicals

  摘要：

  UV irradiation of alpha-(o-alkylphenyl)acetophenones with a methoxy or cyano substituent para to the o-alkyl group of the alpha-aryl ring has revealed that a methoxy group slightly increases the stereoselectivity but not the quantum yield of indanol formation, whereas a cyano group greatly lowers both diastereoselectivity and quantum efficiency, confirming the likelihood that hydrogen-bonding of the hydroxy group to the alpha-phenyl ring plays an important role in the cyclization of the photogenerated triplet 1,5-biradical intermediates.

  'Salen' along: The iridium(III)–salen complex 1 efficiently catalyzes the title reaction of 2‐ethylbenzenesulfonyl azides to give five‐membered sultams with high enantioselectivity. Other 2‐alkyl‐substitued substrates lead to five‐ and six‐membered sultams with high enantioselectivity; the regioselectivity depends upon the substrate and the catalyst used. EDG=electron‐donating group.

  沿'Salen'方向移动：铱（III）-salen配合物1有效催化2-乙基苯磺酰叠氮化物的标题反应，从而产生具有高对映选择性的五元磺胺。其他的被2-烷基取代的底物导致对映体选择性高的五元和六元均聚物。区域选择性取决于所用的底物和催化剂。EDG =给电子基团。

• Oxidation of benzylic methylenes to ketones with Oxone–KBr in aqueous acetonitrile under transition metal free conditions
  作者：Lixia Yin、Jingjing Wu、Juan Xiao、Song Cao

  DOI：10.1016/j.tetlet.2012.06.036

  日期：2012.8

  A green and highly efficient protocol for the oxidation of benzylic methylenes to their corresponding ketones with a combination of Ozone and KBr in aqueous acetonitrile is developed. The (H2O)-O-18 labeling experiment demonstrated that the oxygen introduced into ketone originated from water. A plausible mechanism was also suggested. (c) 2012 Elsevier Ltd. All rights reserved.
