Direct and indirect redox-activation of H2S in the presence of cyclopentene or cyclohexene in MeCN at 25?°C affords the corresponding cycloalkanethiols.
Melamine-(H2SO4)3/melamine-(HNO3)3 instead of H2SO4/HNO3: A safe system for the fast oxidation of thiols and sulfides under solvent-free conditions

Melamine reacted with neat sulfuric acid and fuming nitric acid readily to form two new organic solid acids, namely melamine-(H2SO4)3 and melamine-(HNO3)3. Mixture of them acts as a unique powerful system instead of a hazardous H2SO4/HNO3 system for the direct oxidation of thiols. Also, this system can oxidize the sulfides in the presence of a catalytic amount of KBr and few drops of water. This procedure offers advantages such as very low reaction time, simple work-up, excellent yield and matching with some green chemistry protocols.
FUNCTIONALIZATION OF SATURATED HYDROCARBONS IN THE PRESENCE OF APROTIC ORGANIC SUPERACIDS. 2. SINGLE-STAGE SYNTHESIS OF THIOESTERS R1CO-SR FROM n-ALKANES OR CYCLOALKANES (RH), ELEMENTAL SULFUR, AND COMPLEXES R1COBr*2AlBr3

It has been found for the first time that n-alkanes and cycloalkanes (RH) can interact with elemental sulfur at ca. 20 deg C.These reactions go forward in the presence of aprotic organic superacids with the composition R1CO-SR in satisfactory yields.
