Cyclohexene → Cyclohexylphenethyldichlorosilane

Participants

Reaction Steps

Then into a 100 ml pressure-proof stainless steel reactor; 6.21 g (30.3 millimol) of the above-mentioned phenethyldichlorosilane, 4.47 g (54.4 millimol) of cylcohexene and 0.1 ml of a chloroplatinic acid solution in isopropanol (0.03 mol % relative to phenethyldichlorosilane) were charged and sealed. Reaction was carried out in an oil bath at 100° C. with stirring for 17.5 hours. After completion of reaction, the reacted solution was subjected to vacuum distillation to obtain 5.30 g (18.4 millimol) of cyclohexylphenethyldichlorosilane. This cyclohexylphenethyldichlorosilane had a boiling point of 112.8°~115.4° C./2.0 mmHg. The infrared spectrum of this compound is shown in FIG. 4. There is no characteristic absorption of Si-H at 2100 cm-1. The NMR spectrum is shown in FIG. 9. There are signals of δ value at 1.0~2.0 ppm (Si--CH2 and C--CH2 --); 2.4~3.0 ppm (--CH2 --C6H5) and 7.15 ppm (--C6H 5). The integral ratio thereof was 14:2:5. In the mass spectrum analysis, parent ion was M+ 286.
