要旨:
The N-isopropylated hydrazine radical cations from 7 (22/tBu,iPr) and 9 (22/iPr2) are isolable and are the
first examples of isolable hydrazine radical cations which lack all C,-H bonds being protected as bridgehead carbons
in bicyclic rings. The cyclic voltammogram of 9 shows electrochemically irreversible oxidation and reduction waves
at platinum. It is argued that this results from a gearing effect of the isopropyl groups, which causes the radical cation
from neutral 9 to be generated in an unstable conformation. Kinetic and thermodynamic conformational effects which
cause hydrazine cyclic voltammetry curves to be electrochemically irreversible are contrasted
