Procedure

Terephthaloyl chloride (6.1 g, 0.03 mole) in 30 ml benzene was added dropwise to a mixture of dicyclohexyl hydroxymethyl phosphine oxide and triethylamine at 50° C. maximum. The reaction mixture was heated to reflux for 30 minutes and the product was filtered, washed with water and dried; m.p. 226°-228.5° C.
