Bipotentiometry in Organic Redox Systems. 1. Oxidation of Aromatic Compounds in Trifluoroacetic Acid
Abstract
Bipotentiometric titrations of various polynuclear aromatic hydrocarbons, benzenes substituted with electron-donating groups, and pi- excessive heteroaromatics in trifluoroacetic acid - dichloromethane with lead (IV) or cobalt (III) acetate solution resulted in novel titration curves. Each reagent increment usually resulted in the formation of a potential 'saw tooth,' indicating formation and decay of reversible redox couples; the final titration curves had one or more potential minima regions before the end-point. In almost all instances the titration curve for a given aromatic compound is characteristic, somewhat in the manner of a spectrophotometric curve.
