o -Phosphinophenolate 和o -phosphinothiophenolate是有效的光催化剂,具有很强的还原能力,可在可见光下活化芳基氯化物和溴化物,进行硼化、芳基化和磷酸化。实验和理论研究表明,邻二苯基膦取代基会导致窄的光学间隙并促进系统间交叉进入三重态,从而促进酚盐和苯硫酚作为有效的可见光-光氧化还原催化剂发挥作用。本文提出的结果表明合成改性的酚盐和苯硫酚盐作为光氧化还原催化剂的前景广阔。
planar carbo- and heterocycle containing PADIs were synthesized in up to 97% yield. Moreover, this approach could be applied to curved aromatic scaffold to achieve the respective bowl-shaped PADI. Two-fold annulation was accomplished by employing arene diboronic esters, affording polycyclic aromatic bis(dicarboximides). The optical and electrochemical properties of this broad series of PADIs were explored
