Procedure

To 10.14 g of 1-methylethyl 2,2-dichloro-2-[(ethoxy)phenylphosphinyl]acetate at 60° C. and under a nitrogen atmosphere was added 6.24 g of phosphorus pentachloride in 1 g portions over a 72 hour period. The mixture was stirred an additional 48 hours after addition. Volatile reaction products were distilled at 45°-50° C./0.75 mm Hg leaving 1-methylethyl 2,2-dichloro-2-[(1-chloro)phenylphosphinyl]acetate as a brown oil.
