towards phosphine oxides and phosphonates has been successfully developed through the desulfonative coupling of various sulfones with secondary phosphine oxides and phosphites. This protocol features simple experimental procedures under mild conditions (i. e., catalyst‐ and oxidant‐free, room temperature and open to air). By doing so, a variety of alkynyl, alkenyl and allyl phosphine oxides or phosphonates
通过各种砜与仲膦氧化物和亚磷酸酯的脱磺偶联,已成功开发了一种有效的,实用的氧化膦和膦酸酯的方法。该协议具有在温和条件下(即无催化剂和氧化剂,室温且对空气开放)的简单实验程序。通过这样做,可以以通常良好的反应效率和选择性(31个实例,最高98%的产率)制备各种炔基,烯基和烯丙基膦氧化物或膦酸酯。
