摘要

膦酸氢二酯及其类似物的生物学重要性和现实意义一直是合成有机磷化学各个领域研究的主要动力。然而,建立一种温和环保的方法来避免使用有毒的PCl3仍然是该领域最大的挑战。作为PCl3的潜在替代品,我们研究了利用非均相单原子位点Ni@CPOL-dppp&;PPh3催化剂将廉价绿色无机盐次亚磷酸钠(NaH2PO2)和醇转化为各种H-膦酸二酯[(RO)2P(O)H]并释放H2的进展。值得注意的是,该催化剂表现出了出色的催化性能,可以将各种各样的醇高效地转化为相应的h -膦酸二酯,收率很高。这条新路线完全避免了三氯化磷的使用,为工业和实验室生产氢膦酸二酯提供了一种方便的实际方法。此外,本研究为在均相催化的指导下开发定义明确的多相催化剂提供了有意义的见解。

Bridging Homogeneous and Heterogeneous Catalysis: Ni@CPOL-dppp&PPh3-Catalyzed Symmetric H-Phosphonate Diester Synthesis from Sodium Hypophosphite

Bridging Homogeneous and Heterogeneous Catalysis: Ni@CPOL-dppp&PPh3-Catalyzed Symmetric H-Phosphonate Diester Synthesis from Sodium Hypophosphite
The biological importance and practical significance of H-phosphonate diesters and their analogues have been the major driving forces for research in various areas of synthetic organic phosphorus chemistry. However, establishment of a gentle and environmentally friendly method to avoid use of toxic PCl3 is still the biggest challenge in this area. As potential alternatives to PCl3, we studied the progress in the conversion of cheap and green inorganic salt sodium hypophosphite (NaH2PO2) and alcohol into various H-phosphonate diesters [(RO)2P(O)H] with the release of H2 by using the heterogeneous single-atom site Ni@CPOL-dppp&PPh3 catalyst. Remarkably, the catalyst exhibited outstanding catalytic performance, allowing for the efficient conversion of a wide range of various alcohols to their corresponding H-phosphonate diesters in good to high yields. This new route completely avoids the use of phosphorus trichloride (PCl3) and promises a convenient real process for making H-phosphonate diesters in industry and laboratory. Moreover, the present study provides meaningful insights into the development of well-defined heterogeneous catalysts guided by homogeneous catalysis.
