Presumptive Structures of Activated Complexes in Polarographic Redox Reactions of Unsaturated Organic Compounds. II. Polarographic Oxidations of Aromatic Hydrocarbons, Aromatic Amines, Aromatic Bromides and Benzaldehyde Derivatives, and Polarographic Reductions of Several Kinds of Disubstituted Compounds

Abstract

The theoretically proposed structures of activated complexes in polarographic redox reactions of unsaturated organic compounds were shown to be valid without exception in the cases of the oxidation reactions examined. Additional data supporting the validity of the assumption for reduction reactions were also obtained. The MASP-HMO method was very useful for the calculation of π-stabilization energies of para- and meta-disubstituted aromatic compounds.
