The deoxygenation of a variety of sulfoxides, selenoxides, telluroxides, sulfones, selenones and tellurones has been reported with Mg–MeOH at room temperature in nearly quantitative yields. The deoxygenation is proposed to proceed by SET from Mg to the substrate.

A solvent-free, rapid, and highly selective oxidation of sulfides, selenides, and tellurides (chalcogenides) to the corresponding monoxides (sulfoxides, selenoxides, and telluroxides) or the corresponding dioxides (sulfones, selenones, and tellurones) has been developed using aqueous sodium hypochlorite on solid supports by exposure to microwave. Chemoselectivity and quantitative yields have been attained

Nickel boride has been reported as a convenient and efficient reagent in numerous transformations.1–5 It is superior to many other metal catalysts due to its low cost, ease of preparation and handling, non-pyrophoric nature and easy removal. Unlike its initial applications as a heterogeneous catalyst, nickel boride is used as a reducing agent without aid of hydrogen as it contains adsorbed hydrogen
