Fe(HSO4)3 and Fe(HSO4)3/DMSO as Efficient, Heterogeneous, and Reusable Catalyst Systems for the Oxidative Coupling of Thiols
摘要:
Fe(HSO4)(3) has been used as a heterogeneous, efficient, and recyclable catalyst in ethanol for the selective oxidation of thiols to their corresponding disulfides. The same results were obtained under identical conditions using catalytic amounts of Fe(HSO4)(3) in the presence of DMSO. Different types of aliphatic, aromatic, and heteroaromatic thiols have been used in the reaction, and in all cases the products were obtained in good to excellent yields.
