The procedure of Example 1 is repeated using 5 g (18 mmol) of 2,4-dichloro-1,3-di-tert-butyl-1,3,2,4-diazadiphosphetidine, 18.8 g (36 mmol) of dioctadecylamine, 5 mL (36 mmol) of triethylamine and 200 mL of toluene to give 20 g of a wet solid. Recrystallization of the crude solid with a mixture of 45 mL of acetonitrile and 5 mL of toluene gives 10 g (50% yield) of the title compounds as a white solid melting at 48°-55° C.
