The concept of “umpolung” reactivity of π-allylmetal complexes has been developed as a powerful method for the allylation of aldehydes. This paper describes the photocatalytic umpolung strategy for the synthesis of nucleophilic allylcobalt complexes through a single-electron-transfer (SET) process. This strategy enables the metallaphotoredox allylation of carbonyls with allyl acetate using organic N,N-diisopropylethylamine as the terminal reductant bypassing the use of a stoichiometric amount of metals. Ultraviolet–visible spectroscopy was used to monitor the redox changes of cobalt in the reaction.

亲核性π-烯丙基钴配合物的光催化聚合制备醛的烯丙基化

π-烯丙基金属配合物的“增强”反应性的概念已被开发为醛烯丙基化的有力方法。本文介绍了通过单电子转移(SET)过程合成亲核烯丙基钴配合物的光催化化学合成策略。该策略使得能够使用有机NN-二异丙基乙胺作为末端还原剂,用乙酸烯丙酯使羰基的金属光氧化还原烯丙基化,绕过化学计量量的金属的使用。紫外可见光谱法用于监测反应中钴的氧化还原变化。
