ABSTRACT
The mechanism of reaction acylation of bicyclophosphites by chlorine anhydride of carboxylic acids consists of three stages. The mechanism of the first stage is studied in Ref. [1]. Results of research of the second stage of this reaction are presented in the yielded work. The second stage represents interaction of acetyl chloride and 5-acetyloxymethyl-2-chlorine5-ethyl-1,2,3-dioxaphosphorynan in a gas phase.
