The syntehtic utility of sodium and silver bromates in the presence of Lewis acids as catalysts in organic solvents is described.They are efficient for the oxidation of alcohols, acyloins, and hydroquinones to their corresponding carbonyl compounds.The oxidation coupling of thiols performs well in the absence of the catalysts.Silver bromate is able to transform primary benzylic and saturated alcohols, aldehydes, and primary benzylic carbon-hydrogen bonds to their carboxylic acids efficiently.Secondary benzylic carbon-hydrogen bonds are oxidized to their carbonyl compounds with sodium and silver bromates.
