Efficient and convenient oxidation of sulfides to sulfoxides with molecular oxygen catalyzed by Mn(OAc)2 in ionic liquid [C12mim][NO3]
Abstract
A simple, efficient, and eco-friendly procedure for aerobic oxidation of sulfides catalyzed by Mn(OAc)2/[C12mim][NO3] has been developed. The reactions afford the target products in good to high yields and no over-oxidation was observed. The products can be easily separated, and the catalytic system can be recycled without loss of catalytic activity.
