the reaction. Since various types of alkenylsilanes are prepared by the alkylation of 1-bromo-1-(trimethylsilyl)ethene, 1-bromo-1-(trimethylsilyl)ethene can be utilized as a synthon of phenylthioacetyl anion. The oxygenation of 1-phenylthio-1-(trimethylsilyl)alkenes in the presence of thiophenol gave α-phenylthio thiolesters indicating that the carbon-silicon bond was cleaved exclusively without affecting
Cobalt-Mediated Cross-Coupling Reactions of Primary and Secondary Alkyl Halides with 1-(Trimethylsilyl)ethenyl- and 2-Trimethylsilylethynylmagnesium Reagents
[reaction: see text] This paper describes cobalt-mediated cross-coupling reactions of alkyl halides with 1-(trimethylsilyl)ethenylmagnesium bromide and 2-(trimethylsilyl)ethynylmagnesium bromide, respectively. The cobalt system allows for employing secondary as well as primary alkyl halides as the substrates. The reactions offer facile formations of alkyl-alkenyl and alkyl-alkynyl bonds. The reaction

1,1-Dibromo-2-trialkylsilylcyclopropanes, readily prepared by dibromocyclopropanation of vinyltrialkyl-silanes, react with methyllithium at -90 to 20-degrees-C to give high yields of trialkylsilylcyclopropenes in which the silicon has apparently migrated to C-1.
