We develop an efficient visible-light photoreodox-catalyzed hydrodecarboxylation and deuterodecarboxylation of fatty acids for alkanes and deuterium alkanes. The key to the efficient transformation should attribute to the co-catalysis of the suitable methoxy substituted acridine photocatalyst (Mes-1,3,6,8-tetramethoxy-Acr-3”,5”-dimethoxy-Ph) and the hydrogen atom transfer catalyst 4′,4′-dimethyl diphenyldisulfane
我们为烷烃和氘烷烃开发了一种高效的可见光光氧化还原催化的脂肪酸加氢脱羧和氘脱羧。高效转化的关键在于合适的甲氧基取代吖啶光催化剂(Mes-1,3,6,8-tetramethoxy-Acr-3”,5”-dimethoxy-Ph)的共催化和氢原子转移催化剂 4',4'-二甲基二苯二硫烷,可能通过促进活性烷基自由基猝灭以克服竞争性均偶联产物,烯烃通过歧化反应,裂解产物通过 C-C 键 β-断裂。
