Procedure

To a solution of ethyl ethylphenylphosphinate (2 g, 10 mmol) in benzene (200 mL) is added oxalyl chloride (1.3 mL, 15 mmol). The mixture is stirred for 3 hours at room temperature. The volatiles are removed on a rotary evaporater and the product is dried under vacuum for 12 hours to give ethylphenylphosphinic chloride as an oil.
