Versuchsvorschrift

To a solution of 8 g (121.2 mmol) of phosphonous acid in 30 ml of anhydrous ethanol, cooled to 0° C., are added dropwise 22.21 g (121.2 mmol) of diphenylmethylamine, while taking care to ensure that the temperature does not exceed 25° C. After addition, a white precipitate forms, to which 200 ml of diethyl ether are added. The precipitate is filtered off, rinsed with diethyl ether and then dried. 22.66 g of product are recovered (yield=98.2%).
