Abstract
Magnetic iron oxide nanoparticles (Fe3O4 MNPs) were used as a readily available, highly efficient and recoverable catalyst for the anti-Markovnikov 1,2-addition of thiols to alkenes and alkynes, affording sulfides and vinyl sulfides in excellent yields in short reaction times under mild and solvent-free conditions. This catalyst was also utilized for thia-Michael addition, substitution reaction, ring opening of epoxides, and the synthesis of thiol esters.
