3.1. Electrochemical Evaluation Using the CV approach, the dihydrobenzothienopyranone A1 – A5 catalysts’ N 2 H 4 electrooxidation activities were examined. The results, shown in Figure 1 a-c, compare the CV measurements conducted in both a 1 M KOH solution and a 1 M KOH + 0.5 M N 2 H 4 solution. As the catalysts were organic-based and lacked precious metals such as Pd, Pt, or Au, no distinct oxidation peaks were observed in the voltammograms.

1 Introduction Sulfur heterocycles are among the most important classes of heterocyclic molecules. In fact, S-containing heterocyclic cores are present in a plethora of pharmacologically important molecules, which display a large variety of bioactivities, including anticancer, antidiabetic, antimicrobial, antihypertensive, antiviral, and antinflammatory activities [1, 2]. Moreover, sulfur heterocycles find large application in materials science [3].
