Michaelis–Arbuzov reaction of carboxylic acids and triaryl phosphites for preparing aryl phosphonates under anhydride-free conditions has been reported. In this context, triaryl phosphites serve as both reagents for activating the carboxylic acids and substrates for the reaction. There have been no reports to date of efficient and direct methods for the in situ activation of carboxylic acids using triaryl phosphites
据报道,在无酸酐条件下,通过钯催化的羧酸和亚磷酸三芳基酯的脱羰米氏-阿布佐夫反应制备膦酸芳基酯。在本文中,亚磷酸三芳基酯既充当用于活化羧酸的试剂又充当反应的底物。迄今为止,还没有关于使用亚磷酸三芳基酯原位活化羧酸的有效且直接的方法的报道。与已知方法相比,该反应避免了有机卤化物的使用,并且对于由亚磷酸三芳基酯和羧酸合成各种膦酸芳基酯具有优异的官能团耐受性。该反应具有可扩展性,适用于合成具有生物活性片段的芳基膦酸酯。
