Abstract

b -Halo-alkyl phosphate or phosphite esters are prepared by reacting a phosphorus trihalide of the formula POX3 or PX3 respectively, where X represents a halogen atom with a b -haloalcohol in the presence of a Friedel-Crafts catalyst. The preferred alcohols are primary alcohols containing at least one halogen atom in the b -position to the hydroxy group. The catalysts include the halides of aluminium, tin, titanium, iron, zinc and magnesium, and boron trifluoride, and are preferably freshly prepared. They may be added as such to the reaction mixture or prepared in situ by adding the appropriate metal to the reaction mixture. The reaction may be effected by mixing the reactants in the presence of the catalyst, or an inert solvent or diluent may be used. The reaction may be carried out at room temperature, or at temperatures of from -10 DEG to 100 DEG C. It may be carried out under reflux or under reduced pressure, or an inert gas may be passed through the reaction mixture to remove hydrogen halide formed in the reaction. Esters containing residual halogen atoms on the phosphorus atom are produced by using a stoichiometric deficiency of the halo-alcohol. Specified alcohols are 2,3-dibromo-, 2,3-dichloro-, 2,3-di-iodo-, 2,3-difluoro-, and 2-bromopropanol, 2-chloro-, and 2-bromoethanol, and 2,3-dibromobutanol.
