Abstract

In the course of our continuing studies1 on the synthetic reactions catalyzed by copper isonitrile complexes, it has been found that metallic copper and Cu2O are dissolved in excess of isonitrile under nitrogen. The mixture of metallic copper or Cu2O with isonitrile has been characterized spectroscopically. Esr spectrum of the mixture of metallic copper and isonitrile showed an unresolved absorption band (g value = 2.0041), suggesting a species of Cu(O) isonitrile complex. Moreover, esr spectra3 of the mixture of metallic copper or Cu2O and π-substrates such as p- and m-dinitrobenzene, nitrobenzene, benzoquinone, fluorene and tetracyanoethylene in isonitrile exhibited the resolved signals of the corresponding organic radical anions.
