Polarography of 5-arylfurfurals in aqueous alcohol media

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The reduction of 5-arylfurfurals on a dropping mercury electrode in aqueous alcohol media proceeds via the same mechanism as the reduction of unsubstituted furfural; the reduction wave of the anion radical of 5-arylfurfurals was detected for the first time. The E1/2 values correlate with the σ constants of the substituents in the para position of the phenyl ring, and the correlation coefficient depends on the pH of the medium; this is determined by the different contributions of the protonation reactions after transfer of the first electron for compounds of the investigated series.
