Abstract

2-Aryl-3,4-diphenyl-5-diphenylylpyrroles and the corresponding radicals were synthesized. The rates of decolorization of the solutions of the radicals in air are described by a second-order equation with respect to the radical, and the logarithms of the rate constants of this reaction correlate with the total Hammett σ constants of the substituents.
