Abstract

Abstract: Twenty-one new phosphorus compounds were synthesized by the reaction of O,O-dialkyl-α-chloroacetoxyalkyl phosphonates and sodium salt of 3-hydroxymethylbenzoxazolone.Their structures were confirmed by means of elementary analysis,IR,¹H and ³¹P NMR and MS.The possible mechanism is that the unsteady reactive intermediate reacting from reactants undergoes intramolecular electron migration rearrangement to form the products.

Key words: 3-Hydroxymethylbenzoxazolone, Synthesis, Reaction mechanism, Intramolecular electron migration rearrangement
