Servis, Kenneth L. published the artcileNMR isotope shifts as a probe of electronic structure, HPLC of Formula: 594-81-0, the publication is Journal of the American Chemical Society (1985), 107(24), 7186-7, database is CAplus.
The β-D isotope effects on the C-13 chem. shifts of 2,3-dimethyl-2-butene, 2,3-dimethyl-2-butene bromonium ion, and 2,3-dimethyl-2-butene mercurinium ion suggests that these cationic derivatives have different electronic structures. The β-D isotope effect in the bromonium ion is pos. (downfield shift) while that in the mercurinium ion is neg. (upfield shift). A comparison with β-D isotope shifts in other cations suggests that the β effects can be related to the electronic structure of these ions.
