Versuchsvorschrift

To 14.0 g. (0.05 m.) of the ammonium salt of dicyclohexylphosphinodithioic acid in 250 mls. of acetone was added 16.67 g. (0.05 m.) of n-octadecylbromide and the mixture was refluxed for 15 hours. The precipitate was then separated by filtration and the filtrate was cooled to precipitate a crystalline solid. The crystalline material was filtered off and recrystallized from acetone to obtain 20 g. (77.8% yield) of product which melted at 67°-69° C.
