Hydrosilylation of 2-phenylpropene with dichloromethylsilane and transformations of the resulting adduct

2-Phenylpropene was hydrosilylated with dichloromethylsilane in the presenc e of H2PtCl6 to synthesize dichloromethyl(2-phenylpropyl)silane. The latter was reacted with methanol in the presence of carbamide to obtain dimethoxy methyl(2-phenylpropyl)silane whose reaction with methylmagnesium iodide gav e methoxydimethyl(2-phenylpropyl)silane Treatment of the latter with 40% HF gave fluorodimethyl(2-phenylpropy)silane which was reacted with BrMgC drop CH to obtain dimethylethynyl(2-phenylpropyl)silane.
