The hydrolysis of phosphinic esters is an important transformation that may be performed under acidic or basic conditions on conventional heating. A series of cyclic phosphinates, 1-alkoxy-3-methyl or 3,4-dimethylphospholane oxides, has now been hydrolyzed under microwave (MW) conditions in the presence of 0.1 or 0.5 equivalents of p -toluenesulfonic acid that served not only as the catalyst but also as a MW absorber. The later phenomenon was proved separately. The pseudo-first-order rate constants for the hydrolyses performed by the new approach were determined and a reactivity order was setup. The model reactions investigated were transplanted into flow MW accomplishment. Graphical abstract

在 PTSA 作为催化剂和作为 MW 吸收剂的情况下，MW 辅助次膦酸盐水解

次膦酸酯的水解是一种重要的转化，可以在酸性或碱性条件下在常规加热下进行。一系列环状次膦酸盐、1-烷氧基-3-甲基或 3,4-二甲基膦氧化物现已在微波 (MW) 条件下在 0.1 或 0.5 当量的对甲苯磺酸存在下水解催化剂，也可作为 MW 吸收剂。后一种现象单独证明。确定了由新方法进行的水解的准一级速率常数，并设置了反应顺序。将所研究的模型反应移植到流 MW 实现中。图形概要
