A visible‐light mediated γ‐hydroxyalkylation of ketones via C(sp³)‐H functionalization has been developed under redox neutral conditions. This protocol relies on the iminyl radical‐triggered 1,5‐HAT followed by oxyalkylation of alkenes, wherein C−C and C−O bonds were constructed in one step. This three‐component reaction features mild conditions, wide substrate scope and excellent functional group tolerance, thus providing a facile and highly efficient access to complex valuable ketones.

通过串联1,5-HAT的远程C（sp3）-H键的亚氨基自由基介导的受控羟烷基化和芳基烯烃的双官能化

在氧化还原中性条件下，通过C（sp ³）-H官能团形成了可见光介导的酮的γ-羟烷基化反应。该协议依赖于亚胺基引发的1,5-HAT，然后进行烯烃的氧烷基化，其中CC和C-O键是一步构建的。该三组分反应具有温和的条件，宽的底物范围和出色的官能团耐受性，因此可以轻松高效地获得复杂的有价值的酮。
