Solvolytic behaviour of cis- and trans-[5-2H1]cyclo-octyl p-bromo-benzenesulphonate—a stereospecific, remote ε-deuterium isotope effect
Abstract
cis-and trans-5-Deuteriocyclo-octyl p-bromobenzenesulphonates have been prepared and their kinetic isotope effects and extent of transannular (C-5-→ C-1) hydride shift have been determined for buffered acetolysis. The trans-isomer shows a significant effect (kH/kD= 1.12) and there is a 10:1 preference for trans-5-hydride migration.
