Vorschrift

n-Nonadecylmagnesium bromide (0.33 moles) in ethyl ether is slowly added to 0.33 mole of diethylcarbonate in 100 ml diethyl ether and stirred for one hour at 30° C. (nitrogen atmosphere). n-Tetradecylmagnesium bromide (0.33 mole) is slowly added to the solution and stirred for one hour at 30° C. n-Decylmagnesium bromide (0.33 mole) is slowly added to the solution and stirred for one hour at 30° C. The mixture is then slowly poured into 600 ml of a cold 10% HCl solution. The organic layer is dried with magnasium sulfate and the ethyl ether evaporated off to give n-nonadecyl-n-tetradecyl-n-decylcarbinol.
