For the first time scandium triflate was supported on modified Fe3O4 magnetic nanoparticles [MNPs-PhSO3-Sc(OTf)2] and characterized using scanning electron microscopy (SEM), inductively coupled plasma analysis (
Laccase-TEMPO as an efficient catalyst system for metal- and halogen-free aerobic oxidation of thioethers to sulfoxides in aqueous media at ambient conditions

We present for the first time an eco-friendly procedure for the aerobic oxidation of thioethers to sulfoxides using laccase-TEMPO catalyst system. This catalyst system allows for simpler (easy work-up) and greener methodologies (room temperature, phosphate buffer) while keeping high reaction yields and selectivity. This work is superior to others due to free from any transition metal and halide co-catalysts.
Solvent, metal and halogen-free synthesis of sulfoxides by using a recoverable heterogeneous urea-hydrogen peroxide silica-based oxidative catalytic system
