- Thiolation of cycloalkenes C5, C6 by redox-activation of hydrogen sulfide
-
Direct and indirect redox-activation of H2S in the presence of cyclopentene or cyclohexene in MeCN at 25?°C affords the corresponding cycloalkanethiols.

- Redox mediators of hydrogen sulfide oxidation in reactions with cycloalkanes
-
An indirect electrochemical method for thiolation of cycloalkanes C5-C7 has been suggested. The method is based on a new approach to activation of hydrogen sulfide by redox mediators.
