METHOD FOR THE MANUFACTURE OF COMPOUNDS CONTAINING AN ALPHA-OXYPHOSPHORUS GROUP BY USING AN ACTIVATOR

摘要

A method for the manufacture of compounds containing an ±-oxy phosphorus group is disclosed. A compound containing an ±-oxy carboxylic acid group is reacted in a specific equivalent ratio with a nucleophilic P component, wherein the phosphorus atom has the oxidation state +1 or +3, whereby the compound containing an ±-oxy carboxylic acid group or the nucleophilic P component or both are first reacted with an activator, followed by conducting the reaction and adding a water at the end of the reaction. The compounds containing an ±-oxy phosphorus group formed are then recovered.
