The mechanism of electroreduction of 9-triptindanone (1), 9,10-triptindanedione (2), and 9,10,11-triptindanetrione (3) was studied by use of the cyclic voltammetric method. All carbonyl groups were reduced giving one, two, and three one-electron cathodic peaks for 1, 2, and 3, respectively and the corresponding oxidation peaks. The first electron transfer is reversible and the radical anions formed are stable. Additional small peaks for 2 and 3 were discussed in terms of an adsorption of reactants and intermediates and their reactions with the participation of supporting electrolyte cations as well as the residual water.
