Reaction Steps
Three drops of a 30% strength solution of hexachloroplatinic acid in isopropanol were added with the aid of a pipette to a mixture of 234 g (1.37 mol) of 3-(3-chloro-4-fluorophenyl)propene and 261 g (1.45 mol) of (4-ethoxyphenyl)dimethylsilane. After a short time, an exothermic reaction took place and the mixture warmed to about 130° C. After cooling, the product was distilled in vacuo. 392 g (82%) of (4-ethoxyphenyl)-(dimethyl)-(3-(3-chloro-4-fluorophenyl)propyl)silane were obtained as a colorless oil of b.p.0.1 =165°-170° C., the purity of which was determined to be 97.4% by gas chromatography.
