A direct catalytic anti-Markovnikov addition of carboxylic acids to alkenes is reported. The catalyst system is comprised of the Fukuzumi acridinium photooxidant (1) and a substoichiometric quantity of a hydrogen-atom donor. Oxidizable olefins, such as styrenes, trisubstituted aliphatic alkenes, and enamides, can be employed along with a variety of carboxylic acids to afford the anti-Markovnikov addition adducts exclusively. A deuterium-labeling experiment lends insight to the potential mechanism.
本文报道了羧酸与烯烃的直接反马氏加成。该催化剂体系由 Fukuzumi 吖啶鎓光氧化剂(1)和亚化学计量的氢供体组成。可使用可氧化的烯烃,如苯乙烯、三取代脂肪族烯烃和烯酰胺,以及各种羧酸,以专一地得到反马氏加成加合物。氘标记实验为潜在的反应机制提供了线索。
