Easily reachable electron-poor/rich primary and secondary benzylic phosphates are suitably used as substrates for Friedel–Crafts benzylation reactions with only 1.2 equiv activated/deactivated arenes (no additional solvent) to access structurally and electronically diverse polyarylated alkanes with excellent yields and selectivities at room temperature. Specifically, diversely substituted di/triarylmethanes
易于获得的电子贫乏/富集的伯和仲苄基磷酸酯适合用作Friedel-Crafts苄基化反应的底物,仅需1.2当量的活化/失活芳烃(无需额外的溶剂)即可获得结构和电子多样的多芳基化烷烃,收率和选择性很好。室内温度。特别是,使用此方法可在2-30分钟内生成不同取代的二/三芳基甲烷。只需调节磷酸盐,即可通过此途径轻松实现大量贫电子的聚芳基烷烃。
