The N-isopropylated hydrazine radicalcations from 7 (22/tBu,iPr) and 9 (22/iPr 2 ) are isolable and are the first examples of isolable hydrazine radicalcations which lack all Ca-H bonds being protected as bridgehead carbons in bicyclic rings. The cyclic voltammogram of 9 shows electrochemically irrevesible oxidation and reduction waves at platinum. It is argued that this results from a gearing effect
