Reaction Steps

Following the procedure of Example 21B, 98 mL (101.33 g, 0.555 mole) of (chloro)vinylmethylphenylsilane was added to the cooled lithium ethenoxide solution prepared in Part A. After work-up and distillation as described in Example 21B, there was obtained 65.21 g (68% yield) of (ethenyloxy)vinylmethylphenylsilane distilling at 78.8°/5.0° mm-80.0°/4.8 mm. The 1H NMR Spectrum (Cl3CD) exhibited resonances at δ=0.50 ppm (CH3 --Si), ~4.1 and 4.5 ppm (CH2 of vinyl on oxygen), a complicated multiline pattern at δ=5.7-6.6 ppm (vinyl group on silicon and the CH of the vinyl group on oxygen) and at δ=7.2-7.7 ppm (C6H5) with the relative intensities consistent with (ethenyloxy)vinylmethylphenylsilane.
