visible light-mediated atom transfer radical addition (ATRA) of haloalkanes onto alkenes and alkynes using the reductive and oxidative quenching of [IrdF(CF(3))ppy}(2)(dtbbpy)]PF(6) and [Ru(bpy)(3)]Cl(2) is presented. Initial investigations indicated that the oxidative quenching of photocatalysts could effectively be utilized for ATRA, and since that report, the protocol has been expanded by broadening
在此,使用 [IrdF(CF(3))ppy}(2)(dtbbpy)]PF( 6) 和 [Ru(bpy)(3)]Cl(2)。初步调查表明,光催化剂的氧化猝灭可以有效地用于 ATRA,自该报告以来,该协议通过扩大光催化剂、底物和溶剂方面的反应范围进行了扩展。此外,进一步修改反应条件允许使用 [Ru(bpy)(3)]Cl(2) 和抗坏血酸钠作为牺牲电子供体的还原淬火循环,将全氟烷基碘化物有效地 ATRA 转化为烯烃和炔烃。
