Notizen:
Deuterium isotope effects on 13C NMR chemical shifts, (2H/1H)nΔ(13C), of 2-methylene-d2-adamantane, 4-methylene-d2-2-adamantanone and 6-methylene-d2-2-adamantanone are presented. Long-range effects (4Δ, 5Δ and 6Δ) in a range from 5 to - 23 ppb were observed. The results for 5Δ and 6Δ are explained in terms of cross-ring field effects resulting from the change of dipole due to deuterium substitution.
