| Abstract: | Stereoisomeric bicyclic tert-alcohols afforded identical ring-expansion products via cationic anti-Markovnikov rearrangement from perpendicular tert-cations into identical six-membered ring secondary cations by the treatment with TiCl4. These results provide evidence that the reaction takes place by the cationic stepwise mechanism. reaction: see text] |
