oxidative allylic C(sp3)–H arylation by radical relay using a broad range of heteroaryl boronic acids with inexpensive and readily available unactivated terminal and internal olefins. This C(sp2)–C(sp3) allyl coupling has the advantage of using cheap, abundant, and nontoxic Cu2O without the need to use prefunctionalized alkenes, thus offering an alternative method to allylic arylation reactions that employ
在本文中,我们介绍了使用广泛的杂芳基硼酸与廉价且易于获得的未活化末端和内部烯烃通过自由基中继进行的区域选择性Cu催化的氧化烯丙基C(sp 3)-H芳基化反应。这种C(sp 2)–C(sp 3)烯丙基偶联的优点是无需使用预官能化的烯烃即可使用廉价,丰富且无毒的Cu 2 O,从而为采用更传统偶联的烯丙基芳基化反应提供了另一种方法与预先安装的离队(LG)处于同盟位置的合作伙伴。
