# What's the mechanism for the oxidation of primary alcohol to carboxylic acid with HNO3? [closed]

Can someone help me find the mechanism for this reaction. I've been looking for it, but I haven't found it. Thank you.

The reaction starts with the formation of an organic nitric acid ester (as these compounds are dangerously unstable, as Uncle Al already pointed out, I would not recommend to use nitric acid for this oxidation). The negatively charged nitrate oxygen abstracts an alpha proton from the alkyl group, and $\ce{HNO2}$ is eliminated, yielding the aldehyde. Nucleophilic attack of nitrate on the carbonyl group and subsequent elimination of another equivalent $\ce{HNO2}$ finally yields the carboxylate.
