Jones oxidation - Wikipedia

WebCarboxylic acids are very widely used synthons in the synthesis of pharmaceuticals and fine chemicals. One route to prepare these compounds is by the oxidation of primary alcohols. Often, aldehydes are intermediates (or indeed the target of choice), and many reagents employed for aldehyde synthesis will over-oxidize aldehydes to carboxylic ... WebThe oxidation of primary allylic and benzylic alcohols gives aldehydes. Jones described for the first time a conveniently and safe procedure for a chromium (VI)-based oxidation, that paved the way for some further developments such as Collins Reaction and pyridinium dichromate , which also enabled the oxidation of primary alcohols to aldehydes.
