Sherpa Romeo green journal. Permission to archive accepted author manuscript.This review is a critical overview of the literature on electrochemistry of unsaturated ring
compounds containing bonds between Group 15 and Group 16 elements (principally S and N),
including metallacycles. It contains a detailed compilation of measured redox potentials and the
conditions under which these were obtained for over 200 compounds. An introduction to the
application of solution electrochemistry to this class of compounds is provided, and the relevance
of such measurements to materials design is discussed.Ye
