Reactions of phosphorodiamidous acid esters with (alpha-halocarbonyl compounds

Abstract

Reactions of ethyl and tert-butyl phosphorodiamidites with chloroacetone, bromoacetone, and alpha-chloroethyl acetate were studied. The reaction pathway is determined by the structure of the intermediate quasiphosphonium compound responsible for the formation of the Arbuzov product as well as for the occurrence of the amonalous reaction yielding vinyl phosphate.
