Abstract

A simple, efficient, and metal-free method was developed for the synthesis of phosphoroamidates. In essence, a mixture of sodium periodate (NaIO4) and hydroxylamine (NH2OH⸱HCl) was used in stoichiometric amounts to execute the phosphoramidation reaction of aromatic amines and triethyl phosphites at room temperature, in open air. This method offers a practical synthesis route to afford a diverse range of phosphoroamidates via the construction of P − N bonds, with excellent functional group compatibility and good yields under mild conditions.
