実験手順

Decylmagnesium bromide (0.66 mole) in ethyl ether is slowly added to 0.33 moles of diethylcarbonate in 100 ml ethyl ether and stirred for one hour at 30° C. (nitrogen atmosphere). Tetradecylmagnesium bromide (0.33 moles) 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 magnesium sulfate and the ethyl ether evaporated off to give di-n-decyl-n-tetradecylcarbinol.
