反応手順
A few drops of a 30% solution of hexachloroplatinic acid in isopropanol are added twice at 22° C. to a mixture of 2.98 mol of 4-fluoro-3-phenoxyphenylallylbenzene (98.9% pure, 687 g) and 3.24 mol of 4-ethoxyphenyl(dimethyl)silane (595 g, 97.9% pure). After an induction phase of 11/2 hours, spontaneous heating to 130° C. takes place. After stirring is continued for a short period, 259 g of forerun are distilled off in a high vacuum of 0.4-0.15 mbar, followed by 1003 g of product (98.7% pure by GC). This corresponds to a yield of 81.4% of theory.
