摘要: Abstract We have studied electron spin resonance (ESR) spectroscopy during the oxidation of pyrrole and its derivatives in presence traps order to clarify polymerization mechanism pyrrole. When monomer was chemically oxidized solution containing nitrosobenzene, paramagnetic species (the ESR spectrum which is assigned C 6 H 5 NHO . ) detected. No direct trapping σ-radical strongly suggests that progresses not through neutral but cationic π-radical monomer.
