Synthesis of vinyl- and 2-halovinyl-silanes

Summary

• 1. A method was developed for the synthesis in good yield and in simple apparatus of dichloromethyl-vinyl- and dichloro(2-chlorovinyl)methyl-silanes by the high-temperature condensation of CH₃SiHCl₂ with vinyl chloride and with cis-l,2-dichloroethane respectively.

• 2. In the dehydrobromination of Cl₃SiCHBrCH₂Br, quinoline eliminates the β-bromine atom and aluminum chloride the α-bromine atom.

• 3. (1-Bromovinyl)- and (2-bromovinyl)-trimethylsilanes form reactive Grignard reagents in tetrahydrofuran.
