The Dess–Martin oxidation is an organic reaction for the oxidation of primary alcohols to aldehydes and secondary alcohols to ketones using Dess-Martin periodinane. It is named after the American chemists Daniel Benjamin Dess and James Cullen Martin who developed the periodinane reagent in 1983.
The reaction uses a hypervalent iodine reagent similar to IBX to selectively and mildly oxidize alcohols to aldehydes or ketones. The reaction is commonly conducted in chlorinated solvents such as dichloromethane or chloroform. The reaction can be done at room temperature and is quickly complete. Many other functional groups will not be affected by this reaction.
The Dess-Martin oxidation may be preferable to other oxidation reactions as it is very mild, avoids the use of toxic chromium reagents, does not require large excess or co-oxidants, and for its ease of work up.
The acceleration of the Dess–Martin oxidation reaction using water has been shown by Meyer and Schreiber.
