Abstract
The synthesis of endo- and exo-norbornyl-5,6-d2 p-br omobenzenesulfonates is d escribed. The rate constants of the acetolysis
were measured a nd an isotope effect was obser v ed in the rea ction
of the exo-isomer. This result is in agreement with the mechanism
proposed by Roberts and indicates that the 1,3-hydride shift o ccurs
in the rate determining step.
