Abstract The chemoselective reduction of a wide range of N ‐oxides and sulfoxides with alcohols is achieved using a carbon‐supported dioxo‐molybdenum ( Mo@C ) catalyst. Of the 10 alcohols screened, benzyl alcohol exhibits the highest reduction efficiency. A variety of N ‐oxide and both aromatic and aliphatic sulfoxide substrates bearing halogens as well as additional reducible functionalities are efficiently and chemoselectively reduced with benzyl alcohol. Chemoselective N ‐oxide reduction is effected even in the presence of potentially competing sulfoxide moieties. In addition, the Mo@C catalyst is air‐ and moisture‐stable, and is easily separated from the reaction mixture and then re‐subjected to reaction conditions over multiple cycles without significant reactivity or selectivity degradation. The high stability and recyclability of the catalyst, paired with its low toxicity and use of earth‐abundant elements makes it an environmentally friendly catalytic system.
