Versuchsvorschrift

A 20-ml eggplant type flask was purged with nitrogen, and charged with 2.5 g (10.7 mmol) of 5-hexenyl 2-nitrobenzyl ether, 1.56 g (12.8 mmol) of trimethoxysilane, and an infinitesimal amount of hydrogen hexachloroplatinate(IV) hexahydrate (H2PtCl6·6H2O), followed by stirring at 37° C. for 30 minutes. Thereafter, the bath temperature was raised to 100° C., and the reaction was completed in 2 hours. After the temperature was returned to room temperature, the reaction mixture was purified by vacuum distillation using a short path. From the second fraction (0.2 mmHg/123–125° C.), 1.98 g of the desired product was obtained in a 52% yield.
