unusual because it generates multiple different types of reactive intermediates simultaneously that provide access to (i) silyl radical reactions, (ii) hydrogen atom transfer reactions to closed shell molecules and to radicals, (iii) electron transfer reductions and (iv) hydride ion chemistry, giving scope for unprecedented outcomes. Until now, reactions with this reagent pair have generally been explained
叔丁醇钾和三乙基硅烷的组合是不常见的,因为它会同时生成多种不同类型的反应性中间体,这些中间体可提供(i)甲硅烷基自由基反应,(ii)氢原子转移反应至封闭的壳分子和自由基,(iii)电子转移减少和(iv)氢化物离子化学反应,为取得前所未有的成果提供了空间。到目前为止,通常已参考其中一种中间体解释了与该试剂对的反应,但现在我们着重介绍它们之间的相互作用和竞争。
