Homologation Reaction of γ-Silicon Substituted Allylic Alcohols Using Organoaluminium Reagents and Diiodomethane

Article abstract of DOI:10.1246/cl.1992.2353

One carbon homologation reaction of γ-silicon substituted allylic alcohols was found to proceed by the treatment with triethylaluminium followed by diethylaluminium chloride and diiodomethane to afford homoallylic iodides instead of the corresponding cyclopropanes.Silicon function introduced to γ-position was crucial for the homologation reaction.
