Versuchsvorschrift

To a suspension of 28.99 g of 60% sodium hydride in 350 ml of N,N-dimethylformamide, cooled to 0° C. and under argon is added 60 g of hydroquinone in 450 ml of N,N-dimethylformamide with stirring over 40 minutes. After an additional 30 minutes, 450 ml of tetrahydrofuran is added followed by 192 g of 1-iodohexadecane over one hour. The mixture is stirred at room temperature for 3 hours. The reaction mixture is poured into dilute hydrochloric acid and extracted with chloroform. The organic layer is washed with water, dried and evaporated to give the desired product as an oil.
