Abstract
Electrochemical behavior of [1,2-b]selenophenes and 4H-selenochromenes in organic media and their interaction with hydrogen sulfide have been studied. In aprotic solvents (CH2 Cl2 and CH3 CN), the organoselenium compounds are oxidized at anode to give cation-radicals. In the presence of hydrogen sulfide, at its oxidation potential (1.60 V) [1,2-b]selenophenes and 4H-selenochromenes undergo recyclization into corresponding thiophenes and thiochromenes. The recyclization yielding sulfur analogs have been studied in the presence of organic electromediators, including the transition metal complex with redox-active ligands, as well.
