Sodium bromite (S. B., NaBrO<SUB>2</SUB>) is hitherto known only in the form of impure aqueous solution and used in desizing of fiber and slime control practically. Recently, hydrate and anhydrous forms of S. B. have been prepared as a pure solid reagent. In this article, stability, electrochemical properties and applications of S. B. in oxidation or bromination are described. S. B. oxidizes prim. alcohols to dimerized esters, α, ω-diols to lactones, sec. alcohols to ketones, and sulfides to sulfoxides in good yields and with high selectivities, and interestingly converts olefins into α-bromoketones. S. B. also useful as a solid active bromine for Hofman reaction of carboxylic amides to give amines.
