Electrocatalytic eco-efficient functionalization of white phosphorus
The novel eco-efficient methods to transform white phosphorus into the esters of phosphoric, phosphorous and phosphonic acids, tertiary phosphines and other organophosphorus compounds under conditions of electrochemical catalysis were elaborated. The mechanism of these processes was investigated using the method of cyclic voltammetry and preparative electrolysis.

Electrochemical Oxidation of Metal Dialkyl Phosphites and Their Reaction with Halogens
Electrochemical oxidation of sodium dialkyl phosphites with alkyl radicals of normal structure leads to formation of tetraalkyl pyrophosphites as the main products, while electrochemical oxidation of litium dialkyl phosphites and sodium salts with branched alkyl radicals yields tetraalkyl hypophosphates. The reaction of metal dialkyl phosphites with halogens leads to analogous results.

THE INTERACTION OF PHOSPHITE ESTERS WITH α-IODOKETONES IN THE PRESENCE OF SILVER ION
The reactions of trialkyl phosphites with α-iodoketones in the presence of silver perchlorate or silver tetrafluoroborate yield the corresponding trialkyl phosphates and tetra-alkyl pyrophosphates. Under certain conditions, CIDNP effects indicate the involvement of radical-pairs in the formation of unstable betaine intermediates.
