PREPARATION OF O-(POLYFLUOROALKYL) ALKYLCHLOROPHOSPHONATES AND O-(POLYFLUOROALKYL) ARYL CHLOROPHOSPHATES BY CATALYTIC PHOSPHORYLATION OF POLYFLUOROALKANOLS

A new method was developed for the synthesis of O-(polyfluoroalkyl) alkylchlorophosphonates and 0-(polyfluoroalkyl) aryl chlorophosphates, which consists in phosphorylating polyfluoroalkanols with an excess of the dichlorides of the corresponding phosphorus acids in the presence of salts of the Group II metals.
