Abstract
Four series of tetraphenylpyrrole derivatives were subjected to polarographic oxidation. It was found that electron-donor substituents in the p position of the phenyl ring facilitate polarographic oxidation, while electron-acceptor substituents in the p position hinder it. Correlation equations in coordinates of E1/2 and σ+ were found for all four series, and a correlation between the half-wave potential of polarographic oxidation and the logarithm of the rate constants for decolorization of benzene solutions of the corresponding radicals in air was detected.
