In this contribution, we describe a selective synthesis of phosphoramidates employing diphenyl ditelluride as a simple and readily available organic catalyst. To optimize the reaction conditions, a full factorial design was carried out, demonstrating that the temperature is the critical factor for the P(O)–N bonding formation. The products were obtained in moderate to excellent yields, in mild conditions
在这篇文章中,我们描述了一种使用二苯基二碲化物作为简单且容易获得的有机催化剂的氨基磷酸酯的选择性合成。为了优化反应条件,进行了全因子设计,证明温度是 P(O)-N 键形成的关键因素。产品在温和条件下以中等至优异的产率获得。此外,使用31 P 和125 Te NMR 光谱对中间体进行了表征,证实了反应机理。
