2,6-Dichlorobenzyl chloride (1200 grams) and triethyl phosphate (1115 grams) were charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. The reaction mixture was heated for a period of 60 minutes until the temperature reached 195° C. After this time the mixture was cooled and thereafter distilled under reduced pressure to yield the desired product O,O-diethyl 2,6-dichlorobenzylphosphonate having a boiling point of 158° to 168° C. at 0.4-0.6 mm of Hg pressure.
