The addition of tertiary carbon radicals generated by an Ir-catalyzed visible-light photocatalyst to electron-deficient 1,3-dienes proceeds in good yields to append a δ-substituted β,γ-unsaturated carbonyl fragment to a tertiary alcohol or carboxylic acid precursor and construct a new quaternary carbon center.
铱催化可见光光催化剂生成的叔碳自由基与缺电子的 1,3-二烯加成,以高产率得到δ-取代的β,γ-不饱和羰基片段,加成到叔醇或羧酸前体上,并构建新的季碳中心。
