12.1 g (0.21 mole) of allyl alcohol were added dropwise at room temperature and in a flow of nitrogen to 30.6 g (0.19 mole) of 2-trifluoromethyl acrylic acid chloride, and after addition of the allyl alcohol was completed, the components were stirred for 8 hours at 50° C. Gas chromatography confirmed formation of allyl 1-chloro-2-trifluoromethylpropionate, and a non-reacted substance was removed by distillation under a reduced pressure. The product was combined with 0.04 g of a 10% isopropanol solution of a chloroplatinic acid, and 32.8 g (0.2 moles) of triethoxysilane were added dropwise at 70° C. Following this, the product was stirred for 2 hours at 100° C., and the reaction mixture was subjected to distillation to produce 25.7 g of 3-(2′-trifluoromethyl-3′-chloropropionoxy)propyltriethoxysilane. The 1H-NMR spectrum of the obtained product is shown in FIG. 1. The yield was 36%, and the boiling point of the obtained compound was 118° C./2 mm Hg.
