Intramolecular condensation reactions between allylstannane moieties and carbonyl groups joined by a one carbon tether have been observed, affording silyloxyvinylcyclopropanes. An unexpected dimeric product was formed in one case. Aldehyde derived vinylcyclopropanes have been ring expanded to cyclopentenols.
