  水决定了产物：意外的布朗斯台德酸催化P（III）酯的PO-R裂解，选择性地产生P（O）-H和P（O）-R化合物

  摘要：

  发现水能够确定布朗斯台德酸催化的亚磷酸三烷基酯的C-O裂解反应的选择性：与水一起，该反应在室温下迅速发生，从而定量获得H-膦酸酯的收率。在不加水的情况下，该反应选择性地以高收率提供了烷基膦酸酯，为著名的Michaelis-Arbuzov反应提供了一种新型的无卤化物替代方案。该方法是通用的，因为它可以很容易地扩展到亚膦酸酯和次膦酸酯以及大规模的反应，而催化剂的负载却低得多，从而能够简单，有效和实用地制备相应的有机磷化合物。

  applications. Herein, we report photocatalytic HAT-induced α-C(sp3)–H phosphonylation of aliphatic amines, providing rapid access to structurally diverse α-aminophosphonates from abundant amines. Leveraging intramolecular HAT, radical polar crossover, and an Arbuzov-type phosphonylation cascade, the challenges associated with HAT-induced C(sp3)–H to C(sp3)–P transformation were overcome. This protocol features
