Abstract
Intramolecular homolytic substitution reactions at silicon by vinyl radicals are described.
The reaction can be used for the formation of 5- and 6-membered cyclic alkoxysilanes
bearing a vinyl silane functionality. These processes provide a new entry into highly
substituted vinyl silanes. The reactions occur with moderate to excellent selectivities.
Key words
radical chemistry - silicon - stereoselective synthesis - vinyl silanes - tin
