Secondary oxidant

A rapid and convenient oxidation of secondary alcohols

WebIn seawater, secondary oxidants are often produced that have different characteristics than the primary oxidant. Chlorine, ozone and peracetic acid oxidize the bromide ions in seawater to bromine, which is also an oxidant. If free ammonia is present in the seawater, chlorine and bromine will form chloramines and bromamines, which are also oxidants. The Dess–Martin periodinane is a mild oxidant for the conversion of alcohols to aldehydes or ketones. The reaction is performed under standard conditions, at room temperature, most often in dichloromethane. The reaction takes between half an hour and two hours to complete. The product is then separated from the spent periodinane.
