Activation parameters for intramolecular nucleophilic substitution by carbanions?the insignificant effect of ring strain on cyclisation rates

Activation parameters for the cyclisation of bis-sulphonyl-stabilised carbanions to bis-sulphonylcycloalkanes have been determined; cyclopropanes form nearly a million-fold faster than cyclobutanes and ring strain is a negligible factor in determining reactivity.
