Many quinolones, substituted quinolines and thiones are well known for their biological activity. The redox characteristics of such biological substances may provide valuable information about the redox behaviour in living systems. The present paper is aimed at carrying out a methodical cyclic voltammetric investigation of the peak potential values of 4-methyl/phenyl -3- vinyl quinoline-2(1H) one(MVQ/PVQ), 2-chloro-4- methyl/phenyl -3-vinyl quinoline (CMVQ/CPVQ), 4- methyl/phenyl -3-vinyl quinoline-2(1H)-thione (TMVQ/TPVQ), in tetrahydrofuran (THF) with tetra butyl ammonium bromide (TBAB) as supporting electrolyte at glassy carbon electrode (GCE) with varying scan rate . All the voltammograms showed only irreversible diffusion controlled reduction.
