Phosphorylation of amines, alcohols, and sulfoximines provides various phosphoramidates, phosphorus triesters and sulfoximine-derived phosphoramidates using molecular iodine as a catalyst and H2O2 as the sole oxidant under mild reaction conditions.

Simply heating secondary phosphine oxides and O-benzoylhydroxylamines in the presence of K2CO3 gives phosphinic amides in moderate to excellent yields under air. This method provides a practical and catalyst-free method for the synthesis of various synthetically valuable phosphinic amides.

Reductive radical cyclization of N-allyl-N-dimethylphosphinoyl-2-aminopropyl phenyl selenide using tris(trimethylsilyl)silane (TTMSS) / AIBN under UV irradiation gave the corresponding pyrrolidine in 74% yield and a cis/trans ratio of 10/1 which was superior to thermal cyclization.
