Dynamic 31P NMR spectroscopy was applied to investigate the reactions of o-phenylenedioxytrihalophosphoranes and bis(o-phenylenedioxy)halophosphoranes with epichlorohydrin as a function of the reagent ratio. α-Opening of the epoxide ring predominantly occurs. With excess epichlorohydrin the reaction with o-phenylenedioxytrichlorophosphorane results in formation of pentaalkoxyphosphorane, while in the reaction with o-phenylenedioxytechintribromophosphorane a mixture of phosphate and pentaalkoxyphosphorane is formed.
REACTION OF 2-TERT-BUTOXY-4,5-BENZO-1,3,2-DIOXAPHOSPHOLANE WITH TRIBROMOACETALDEHYDE

The reaction of 2-tert-butoxy-4,5-benzo-1,3,2-dioxaphospholane with tribromoacetaldehyde proceeds by initial halophilic attack on the bromine atom, leading to a product with retention of the P-Br bond (pyrocatechol bromophosphate) and an anion exchange product (pyrocatechol dibromovinylphosphate), and by initial attack at the carbon atom of the C=O group, which is accompanied by the elimination of isobutylene to form an α-hydroxyphosphonate.
