Abstract

Conclusion In conclusion rapid two and threefold degenerate equilibration processes were demonstrated in secondary cyclopropylcarbinyl cations which are of classical carbocation nature. In contrast the primary cyclopropylcarbinyl cation^^.^ are equilibrating non-classical cations. The nature of classical and nonclassical ions thus cannot be differenciated in the context of static vs. equili-brating ions14 as both of these type of ions can belong to either ...
