| Outline of Final Research Achievements |
Nitronyl nitroxides (NN-Rs) and their related radicals have been especially utilized for organic spin sources and their unique spin-related properties have been investigated in view of purely organic ferromagnets, hybrid ferrimagnets, and negative magnetoresistance. NN-Rs are generally prepared via the condensation reactions of a corresponding hydroxyamine with various aldehydes and subsequent oxidation with a stoichiometric amount of oxidant. For the developments of the synthetic strategies for NN-Rs, we have focused on radical-metalloid NN-M systems. We have succeeded in the rapid preparation method of these NN-M. These are found to be stable even under air and could be easily handled. We have also found that that NN-Au, Cu, and Zn can be utilized as reagents of introduction to p-electronic systems via cross coupling reactions. The utility of the present method was demonstrated by the direct synthesis of NN-Rs which could not be prepared via typical condensation-oxidation methods.
