A metal-free method for the dual activation of aryl phosphinate has been developed; the P–H and P–O bonds are sequentially activated by the Tf2O/DMSO system. Without the requirement of metals and unstable P-reagents, this one-pot procedure provides a convenient and practical access to a variety of aryl phosphonates. A mechanism involving twice generation of electrophilic P-species and two SN-processes
开发了一种无金属的芳基次膦酸盐双重活化方法;P-H 和 P-O 键依次被 Tf 2 O/DMSO 系统激活。这种一锅法不需要金属和不稳定的 P 试剂,可以方便实用地获得各种芳基膦酸酯。在对照实验的基础上,提出了涉及两次亲电P-物种生成和两次S -N-过程的机制。
