摘要
有机磷化合物在化工、医药和化肥行业具有重要意义。生产有机磷化合物通常需要使用白磷或 PCl3,而白磷或 PCl3 具有毒性,生产成本高昂。在这项工作中,我们研究了通过电化学途径形成亚磷酸酯的方法,它有可能成为一种更环保的替代品。特别是,通过无机 P 源 H3PO2 和甲醇作为模型构件的氧化偶联,电合成了亚磷酸二甲酯,其远红外效率高达 100%。据推测,该反应是通过电氧化磷自由基的形成,然后将这种活性物质与近端甲醇分子耦合而进行的。
Dimethylphosphite electrosynthesis from inorganic phosphorus building blocks via oxidative coupling†
Organophosphorus compounds carry importance in the chemical, medical, and fertilizer industries. Their production often entails the use of white phosphorus or PCl3, which are toxic and energetically costly to produce. In this work we investigate phosphite ester formation through an electrochemical route which has the potential to serve as a greener alternative. In particular, dimethyl phosphite was electrosynthesized through oxidative coupling of an inorganic P source, H3PO2, and methanol as a model building block with high faradaic efficiencies approaching 100%. The reaction is proposed to proceed through electrooxidative phosphorus radical formation followed by coupling of this reactive species with proximal methanol molecules.
