Abstract

Protonation induced Carbon-13 NMR chemical shifts are measured for five cyclic amines (1-5). The effect of sp3 hybridized positive charge on the chemical shifts of remote carbon atoms in protonated cyclic amines is compared with the effect of sp2 hybridized positive charge on the chemical shifts of remote carbon atoms in arylcyclic carbocations.
