Abstract
1387319 Preparing phosphonic acid dihalides HOECHST AG 25 Oct 1972 [26 Oct 1971 26 Aug 1972] 49237/72 Heading C2P A phosphonic acid dihalide of the formula R-P(O)(Hal) 2 wherein R is an α,#-unsaturated alkenyl group having 2 to 18 carbon atoms, an α,#-unsaturated cycloalkenyl group having 3 to 10 carbon atoms, or a phenyl or benzyl group and wherein R may be substituted by a Cl or Br atom or by a C 1 -C 4 alkyl or -alkoxy group, cyano or CF 3 group and Hal is a halogen atom, is obtained by reacting a corresponding phosphonic or pyrophosphonic acid of the formulae RP(O)(OH) 2 and RP(O)(OH)OP(O)(OH)R, their monothio analogues or their functional derivatives with an acid halide (CO) n Hal 2 in which n is 1 or 2. The preferred acid halide is phosgene and the reaction is suitably effected at from 65‹ to 200‹ C. the acid halide being advantageously introduced into the phosphonic acid derivative optionally dissolved in an inert solvent which is preferably the end product of the reaction. A polymerization inhibitor may be included in the reaction mixture, especially when R is alkenyl. The phosphonic acid may be used in the form of a functional derivative, e.g. a semi-ester, diester, salt, ester halide, anhydride, pyrophosphonic acid ester or semiester or monothio analogue.
