Herein, a new solvent-free synthetic method using P(O)-OH compound and alkyl chloride for phosphinate compounds is disclosed. This transformation proceeds smoothly under the promotion of a lone base and presents the advantages of an easily available raw material source, a simple post treatment process, good functional group tolerance and high reaction efficiency. Good yield was obtained when the reaction was magnified to gram scale, and the molar ratio of P(O)-OH compounds and alkyl chlorides can be decreased to 1:2. This protocol provides a practical method for the preparation of phosphorus derivatives. Furthermore, the reaction mechanism was explored by means of 31P NMR.

A phosphoryl radical-initiated Atherton-Todd-type reaction using air as the radical initiator and CHCl3 as the halogenating reagent for the phosphorylation of alcohols, phenols, and amines has been developed. This novel transformation provides a highly efficient route to important phosphinates, phosphinic amides, and phosphoramidates in up to 99% yield with a broad substrate scope under very mild conditions (48 examples).

An efficient oxygen-phosphoryl bond-forming reaction via iron-catalyzed cross dehydrogenative coupling has been developed. This transformation proceeds efficiently under oxidant- and halide-free reaction conditions with H2 liberation, and represents a straightforward method to prepare valuable organophosphoryl compounds from the readily available alcohols and P(O)-H compounds.
