Silica gel promoted, catalyst-free and solvent-free S-P, Se-P and Te-P bond formations are described. A variety of disulfides coupled with diarylphosphine oxides provide the corresponding phosphinothioates in excellent yields. For the first time, diselenides and ditellurides reacted with dialkyl phosphites under catalyst-free conditions to provide the corresponding phosphoroselenoates and phosphorotelluroates, respectively, in good to excellent yields.
本文描述了硅胶促进、无催化剂和无溶剂的 S-P、Se-P 和 Te-P 键形成。各种二硫化物与二芳基氧化膦偶联，以优异的收率得到相应的亚磷酸硫酯。首次在无催化剂条件下，二硒化物和二碲化物与二烷基亚磷酸酯反应，分别以良好到优异的收率得到相应的亚磷酸硒酯和亚磷酸碲酯。
