Melamine-(H2SO4)3/melamine-(HNO3)3instead of H2SO4/HNO3: a safe system for the fast oxidation of thiols and sulfides under solvent-free conditions
Journal of Sulfur Chemistry Vol. 36, No. 6, 606–612
چکیده
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.
