반응 단계

About 6.21 g (23.5 mMol) of 4-(5-hexenyloxy)-1-trimethylsilyloxy benzene, 3.48 g (23.5 mMol) of pentamethyldisiloxane and 694 mg (17.7 μMol of Pt) of 0.5 percent cyclopentadienylplatinum dichloride solution (dichloromethane) were refluxed for 7 hours in 25 ml of toluene. After the hydrosilylation was complete, the toluene was removed by vacuum distillation on a rotary evaporator. The crude product was purified by chromatography on silica gel. Further chromatography on silica gel using petroleum ether/ethyl acetate mixtures on a Harrison Research chromatotron gave 94 percent pure 4-(1-pentamethyldisiloxanylhexyloxy)phenol as a pale yellow liquid.
