Sodium bromate

Recent Literature

Oxidation of sulfides to sulfoxides with a catalytic amount of ceric ammonium nitrate reagent supported on silica gel has been achieved using stoichiometric sodium bromate as the primary oxidant. The heterogeneous CAN/NaBrO3 reagent enables the use of an organic solvent and simplifies the reaction work-up and product isolation.

The use of NaSO2CF3 and NaBrO3 enables a free-radical bromotrifluoromethylation of olefins. Sodium bromate acts not only as a single-electron oxidant but also as a bromine source.
