A new versatile method for the C–P bond formation of (hetero)aryl halides with trimethyl phosphite via a UV-induced photo-Arbuzov reaction, accessing diverse phosphonate-grafted arenes, heteroarenes and co-facially stacked cyclophanes under mild reaction conditions without the need for catalyst, additives, or base is developed. The UV-induced photo-Arbuzov protocol has a wide synthetic scope with large
一种新的通用方法,用于通过紫外诱导的光 Arbuzov 反应与亚磷酸三甲酯形成(杂)芳基卤化物的 C-P 键,在温和的反应条件下获得不同的膦酸酯接枝芳烃、杂芳烃和共面堆叠的环芳烃,而无需开发了对催化剂、添加剂或碱的需求。UV 诱导的光 Arbuzov 协议具有广泛的合成范围,具有大的官能团兼容性,例如 30 多种衍生物。除了单膦酸盐外,二膦酸盐和三膦酸盐的收率也很高。温和和不含过渡金属的反应条件巩固了该方法合成药物相关化合物和超分子纳米结构材料前体的潜力。
