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

Abstract

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.
