Thermochemical and kinetic study of the carbocation ring contraction of cyclohexylium to methylcyclopentylium.


The isomerization of cyclohexylium to methylcyclopentylium is a model for a key step required in sterol and triterpene biosynthesis and is important in catalytic processes associated with ring-opening reactions in upgrading petroleum fractions. Using high-level, correlated wave function techniques based on QCISD, the mechanism for this isomerization was… (More)
