The electro reduction of some arenotropilidenes and their chromium and iron tricarbonyl complexes in DMF were found to proceed by two electrons represents by one wave, producing the corresponding dianion. The polarograms of arenotropones and their chromium tricarbonyl complexes in DMF consist of two successive reduction waves, each corresponds to 1 F/mol. The reduction mechanism was investigated as well as the number of electrons was determined. Also, the half wave potentials of the ligands were compared with those of their metal tricarbonyl complexes.

Keywords: Polarography, arenotropilidene, DMF
