Radical cations. Part 2. Oxidative dimerization of indolizines: a chemical and electrochemical investigation
Abstract
3-Unsubstituted indolizines undergo oxidative dimerization in the presence of catalytic amounts of FeIII and oxygen. Although much experimental evidence apparently indicates that FeII is reoxidised to FeIII by oxygen, a chain mechanism cannot be envisaged. A chain sequence can be proposed only in the case where a stoicheiometric amount of FeIII is used.
