Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Using EPR we have found that during electrochemical reduction of 5-substituted 2-furaldehydes and 2-thiophenaldehydes, carbon-centered free radicals (products of protonation of radical anions) may form, along with radicals of a different structure, and also π-type radical anions of different conjugated dimers. We have determined the hyperfine structure and measured the values of the constants for the EPR spectra of some of these radicals.
