Trimethylsilyl chloride as an activating agent enables a one-step synthesis of acyl phosphoramidates from a variety of functionalized acyl azides. This modified Staudinger reaction was further adapted to include in situ generation of acyl azides from a broad range of carboxylic acids and hydrazides.
