Reinvestigation of the reaction between sodium diethyl phosphite and diethyl phosphorochloridate. Evidence for a SET process in the formation of a direct P(IV)-P(IV) bond
Alkali metal salts of diethyl phosphites act as nucleophiles or electron donors in reactions with diethyl phosphorochloridate. Evidence is provided that formation of the direct P(IV)-P(IV) bond proceeds via a single electron transfer process (SET) from phosphite anion to phosphorochloridate.

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.

Free-Radical Phosphorylation of Olefins Initiated by Anodic Oxidation
Electrochemical oxidation of lithium and sodium dialkyl phosphites generates dialkyl phosphonyl radicals, which initiate chain free-radical addition of dialkyl phosphites across the alkene multiple bond to form alkyl(cycloalkyl)phosphonates. Alkyl(cycloalkyl)phosphonates are formed simultaneously owing to anodic oxidation of adsorbed primary radical adducts of phosphonyl radical and alkene molecule to give the carbenium cation, followed by deprotonation of the latter.
