-Deuterium Isotope Effects on Solvolysis of 7-Halonorbornyl Brosylates-6-d

The γ-deuterium isotope effects for the solvolysis of anti- and syn-7-chloro-, anti- and.syn-7-bromo-exo-2-norbornyl brosylates-6-endo-d and.syn-7-chloro-exo-2-norbornyl brosylate-5,6-exo,exo-d 2 in 80:20 EtOH–H 2 O, 0.04 M NaOAc at 65° are 1.11 ± 0.01, 1.11 ± 0.01, 1.13 ± 0.01, 1.05 ± 0.01, and 1.11 ± 0.01, respectively. The results indicate that the γ-isotope effect observed in the solvolysis of exo-norbornyl brosylate likely is not derived …
