  NHC-铜氢化物作为化学选择性还原剂：炔烃，烷基三氟甲磺酸酯和烷基卤化物的催化还原

  摘要：

  介绍了NHC-铜催化的末端炔和内部炔的Z选择性半还原，以及NHC-铜催化的伯烷基三氟甲磺酸酯，伯和仲烷基碘和溴化物的还原。这些实施例中证明的高化学选择性说明了氢化铜络合物作为还原剂的温和性质，其在合成化学中的应用超出了它们在还原活化烯烃和羰基化合物方面的传统作用。

• Copper-Catalyzed Reduction of Alkyl Triflates and Iodides: An Efficient Method for the Deoxygenation of Primary and Secondary Alcohols
  作者：Hester Dang、Nick Cox、Gojko Lalic

  DOI：10.1002/anie.201307697

  日期：2014.1.13

  We describe an effective method for catalytic reduction of 1° alkyl sulfonates, and 1° and 2° iodides in the presence of a wide range of functional groups. This Cu‐catalyzed reaction provides a means for the effective deoxygenation of alcohols, as demonstrated by the highly selective reduction of 1° alcohols using a triflation/reduction sequence. A preliminary study of the reaction mechanism suggests

  我们描述了一种在多种官能团存在下催化还原1°烷基磺酸盐以及1°和2°碘化物的有效方法。铜催化的反应为醇的有效脱氧提供了一种手段，正如使用三氟甲磺酸化/还原序列对1°醇的高度选择性还原所证明的那样。对反应机理的初步研究表明，还原反应不涉及自由基中间体。
