Conclusions
-
1.
2, 2, 6, 6-Tetramethyl-4-oxopiperidino-1-oxy free radical was reduced according to the Meerwein-Ponndorf reaction without affecting the free valence.
-
2.
The dipole moments of a number of nitroxides were measured.
-
3.
The distribution of charge and spin density of the unpaired electron in certain nitroxides was evaluated.
-
4.
The preferential conformation of the heterocycle in the investigated free radicals were established.
