A phosphorylation of alkenyl and aryl C–O bonds at room temperature via photoredox/nickel dual catalysis is reported. By starting from easily available and inexpensive sulfonates, a variety of important alkenyl phosphonates and aryl phosphine oxides are generated in moderate to excellent yields. This method features mild reaction conditions, high selectivity, good functional group tolerance, wide substrate
据报道,在室温下,通过光氧化还原/镍双重催化使烯基和芳基C–O键发生磷酸化。通过从容易获得且廉价的磺酸盐开始,可以以中等至极好的收率生成各种重要的烯基膦酸酯和芳基膦氧化物。该方法的特点是反应条件温和,选择性高,官能团耐受性好,底物范围广,可扩展性强。
