Photoredox-catalyzed phosphonylation of bromo-substituted 1,10-phenanthrolines under visible light irradiation was studied. The reaction was shown to proceed under mild conditions with Eosin Y as a photocatalyst in DMSO under blue light irradiation. It is transition-metal-free and affords the target phosphonate-substituted 1,10-phenanthrolines in moderate yields (26-51%) in 22 to 40 h. The rate and selectivity of the reaction depend largely on the position of the bromine atom, as well as on the nature and position of other substituents in the 1,10-phenanthroline core.
研究了可见光照射下光氧化还原催化溴代取代的1,10 - 菲咯啉的膦酰化反应。结果表明，该反应在温和条件下进行，以曙红Y作为光催化剂，在二甲基亚砜中蓝光照射下反应。该反应无过渡金属参与，在22至40小时内以中等产率（26 - 51%）得到目标膦酸酯取代的1,10 - 菲咯啉。反应的速率和选择性很大程度上取决于溴原子的位置，以及1,10 - 菲咯啉核心中其他取代基的性质和位置。
