Here we report a strategy for carbonyl addition with unactivated alkenes using an organic photocatalyst on both aldehyde and ketone substrates. This protocol grants us a good alternative to the traditional Barbier–Grignard allylation that exhibits poor functional group tolerance. With this method the stoichiometric use of metals can be avoided, high atom economy can be achieved and fewer by-products
在这里,我们报告了使用有机光催化剂在醛和酮底物上与未活化的烯烃进行羰基加成的策略。该协议为我们提供了一种很好的替代传统 Barbier-Grignard 烯丙基化的方法,后者表现出较差的官能团耐受性。使用这种方法可以避免
