A mild and general visible light photoredox catalysis-induced intermolecular three-component alkene 1,2-diarylation involving aryl C(sp)-H functionalization is described. The key to controlling the chemoselectivity toward alkene 1,2-diarylation is the employment of a 2,2'-bipyridine base, thus allowing the formation of two new C(sp)-C(sp) bonds via aryl radical formation from aryldiazonium salts, addition across the C[double bond, length as m-dash]C bonds, and aryl C(sp)-H functionalization cascades.
描述了一种温和且通用的可见光光氧化还原催化诱导的分子间三组分烯烃 1,2-二芳基化反应，涉及芳基 C(sp)-H 功能化。控制烯烃 1,2-二芳基化反应化学选择性的关键是使用 2,2'-联吡啶碱，从而允许通过芳基重氮盐形成芳基自由基、加成到 C[双键，长度为 m-dash]C 键以及芳基 C(sp)-H 级联反应来形成两个新的 C(sp)-C(sp)键。
