Halogenated esters of phosphorus-containing acids (III)

Abstract

This invention deals with new phosphorus-containing esters having the formula ##STR1## wherein R represents a divalent hydrocarbon radical containing 1-20 carbon atoms; R' represents X, hydrogen or R"; R" represents a monovalent hydrocarbon radical containing 1-20 carbon atoms; and X represents chlorine or bromine. These new esters are useful particularly as fire retardants, agricultural chemicals, fuel additives, plasticizers, monomers and intermediates for the synthesis of other useful derivatives.
