EFFICIENT OXIDATION OF ORGANIC-COMPOUNDS WITH SODIUM AND SILVER BROMATES NABRO3, AGBRO3, IN NONAQUEOUS SOLVENTS IN THE PRESENCE OF LEWIS-ACIDS

The synthetic utility of sodium and silver bromates in the presence of Lewis acids as catalysts in organic solvents is described. They are e fficient for the oxidation of alcohols, acyloins, and hydroquinones to their corresponding carbonyl compounds. The oxidation coupling of thi ols performs well in the absence of the catalysts. Silver bromate is a ble to transform primary benzylic and saturated alcohols, aldehydes, a nd primary benzylic carbon-hydrogen bonds to their carboxylic acids ef ficiently. Secondary benzylic carbon-hydrogen bonds are oxidized to th eir carbonyl compounds with sodium and silver bromates.
