Procedure

5 ml of trichlorosilane are added to a solution of 0.1 g of H2PtCl6 in 20 ml of dry tetrahydrofuran while stirring. A solution of 14.8 g of hex-5-enyl (E)-3,4-dimethoxycinnamate, dissolved in 20 ml of dry tetrahydrofuran, is carefully added dropwise to this. Thereafter, stirring is carried out for 5 hours at room temperature and then for 16 hours at 50° C. The reaction mixture is concentrated in a vacuum produced by a water-jet pump and is completely freed from the remaining solvent and trichlorosilane by means of an oil pump with a cold trap under reduced pressure. This gives crude 6-trichlorosilanylhexyl (E)-3,4-dimethoxycinnamate, which is dissolved in dry tetrahydrofuran for storage.
