Reaktionsschritte
0.97 mmol of (1-phenylethenyl)oxytrimethylsilane was placed in a 20-ml flask, followed by the addition of 3 ml of pyridine as a solvent. 1.3 mmol of benzenediazonium tetrafluoroborate was added to the flask. The resulting mixture was stirred at 0° C. in a nitrogen atmosphere for 2 hours. The reaction mixture was diluted with diethyl ether and washed with 1.5 N hydrochloric acid, water and a saturated aqueous solution of common salt, successively. The organic phase was dried over magnesium sulfate and distilled under a reduced pressure to remove the solvent. The obtained oily mixture was subjected to silica gel thin-layer chromatography to obtain 0.68 mmol of benzyl phenyl ketone.
