  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]

  日期：——

  The equilibrium constants for the acid-catalysed isomerisation of isopropylidenecycloalkanes to isopropylcycloalkenes have been measured as a function of temperature for the five- to eight-membered rings. The rates of equilibration have been measured, starting from each pure isomer. Together these data permit the construction of approximate energy diagrams for the processes. The results are compared
