Electrochemical behaviour of 3,8-difluorobenzo[c]cinnoline at mercury electrode

Voltametric and coulometric methods have been used to study the electroanal ytical behaviour of 3,8-difluorobenzo[c]cinnoline. The number of electrons transferred, the wave characteristics, diffusion coefficient and reversibil ity of the reactions have been investigated in ethyl alcohol-BR. Adsorption of the molecule on the surface of the mercury drop electrode was analyzed and this phenomena was exploited to calculate the diffusion coefficient of 3,8-difluorobenzo[c]cinnoline. A mechanism for the electrode reaction was p roposed. (C) 2001 Elsevier Science B.V. All rights reserved.
