Abstract

Abstract The substitution effect of different groups (H, NO 2, COOH, Br, Cl, NHCOCH 3, CH 3, OCH 3, OH, and N (C 2 H 5) 2) on the polarographic behaviour of p–substituted 1-phenyl- 3-aminocarbonylpyridinium cations has been investigated, in particular on their half-wave potentials in aqueous phosphate buffers pH 6· 65 (10% DMF) and in anhydrous solutions of dimethylformamide with 0· 05 mol l-1 (nC 4 H 9) 4 N+ BF 4-as supporting electrolyte. The ...
