Primary Amination of ArP(O)-H with (NH)CO as an Ammonia Source under Simple and Mild Conditions and Its Extension to the Construction of Various P-N or P-O Bonds.

A facile and efficient method for the synthesis of primary phosphinamides from ArP(O)-H reagents with stable and readily available ammonium carbonate as an ammonia source is disclosed herein for the first time. This ethyl bromoacetate-mediated primary amination proceeds smoothly under mild and simple conditions, without any metal catalyst or oxidant. Moreover, this method is also appropriate for the reaction of ArP(O)-H with a variety of amines, alcohols, and phenols to construct P-N or P-O bonds, with features of handy operation, good functional group tolerance, and broad substrate scope.
