通过碳-碳键的选择性裂解使分子功能化是合成化学中一种很有吸引力的方法。尽管最近在过渡金属催化和自由基化学方面取得了进展,但碳氢化合物原料中惰性 C sp3 -C sp3键的选择性裂解仍然具有挑战性。文献中报道的例子通常涉及含有氧化还原官能团或高度应变分子的底物。在本文中,我们提出了一个用于 C sp3 –C sp3的切割和功能化的简单方案使用光氧化还原催化在烷基苯中键合。我们的方法采用两种不同的断键途径。对于具有叔苄基取代基的底物,普遍采用碳阳离子耦合电子转移机制。对于具有主要或次要苄基取代基的底物,三重单电子氧化级联是适用的。我们的策略提供了一种实用的方法,可以在没有任何杂原子的情况下切割分子中的惰性 C sp3 -C sp3键,从而产生一级、二级、三级和苄基自由基物种。

Electroreduction of benzylicolefins has been applied to site-selectively hydrogenate such double bonds while other functions that react under regular hydrogenation conditions are present. By the use of water as proton source this protocol also allows deuteration by simply switching to D2O. The applicability of this method was shown by the use of a commercially available electrolysis setup and a broad
苄基烯烃的电还原已应用于位点选择性氢化此类双键,同时存在在常规氢化条件下反应的其他功能。通过使用水作为质子源,该协议还允许通过简单地切换到 D 2 O 进行氘化。该方法的适用性通过使用商用电解装置和广泛的底物范围得到证明。
