Photo-oxidation and Thermal Oxidations of Triptycene Thiols by Aryl Chalcogen Oxides.

ABSTRACT: Oxidation of thiols yield sulfenic acids, which are very unstable intermediates. As sulfenic acids are reactive, they form disulfides in the presence of thiols. However, sulfenic acids also oxidize to sulfinic acids (-SO₂H) and sulfonic acids (-SO₃H) at higher concentrations of oxidants. Hydrogen peroxide is a commonly used oxidant for the oxidation of thiols to yield sulfenic acids. However, hydrogen peroxide also oxidizes other reactive functional groups present in a molecule. In this work, the reaction intermediates arising from the oxidation of sterically hindered thiols by aryl chalcogen oxides, dibenzothiophene S-oxide (DBTO), dibenzoselenophene Se-oxide (DBSeO), and dibenzotellurophene Te-oxide (DBTeO), were investigated.
