- It is used as reagents for the oxidation (including oxidative coupling and cyclization reaction) and dehydrogenation of hydroaromatic compounds. It is useful in the synthesis of aromatized or lactones formed steroids and modified natural products. Metal dioxide such as selenium dioxide and manganese dioxide are also oxidising agents which convert alcohols into ketones, aromatic methyl groups into aldehyde or carboxylic acids, double bonds into alcohols, aldehydes into carboxylic acids, steroidal ketones into secolactones. But several side reactions are expected due to the lack of selectivity. DDQ and substituted quinones provide regioselective effectiveness for the preparation of target intermediates. Phenylbis(trifluoroacetato-O) iodine and Tritylium tetrafluoroborate are also reagent for the dehydrogenation of hydroaromatic compounds.
