Radical reactions play an important role in modern organic synthetic chemistry. The generation of carbon radicals from the homolytic cleavage of carbon–metal bonds has been widely studied as a fundamental step in organometallic chemistry. However, the implementation of this phenomenon in catalysed cascade reactions, that is, an organometallic-radical relay, is a highly challenging undertaking due to
自由基反应在现代有机合成化学中发挥着重要作用。作为有机金属化学的基本步骤,碳-金属键均裂断裂产生碳自由基已被广泛研究。然而,在催化级联反应(即有机金属自由基接力)中实现这种现象是一项极具挑战性的任务,因为这些热力学不利的吸能过程会产生瞬态自由基。在这里,我们公开了一组概念上基于有机金属自由基中继的催化烯烃 1,1-双官能化反应。该策略实现了sp 3 / sp 2的多样性片段和芳基同时引入到末端和内部烯烃的相同碳上,具有出色的化学和区域选择性。这项研究提供了从非自由基原料烯烃和芳基硼酸生成官能化苄基自由基的概念,这些自由基很难通过经典方案获得。
