    en.wikipedia.org/wiki/Schmidt_reaction

    The carboxylic acid Schmidt reaction starts with acylium ion 1 obtained from protonation and loss of water. Reaction with hydrazoic acid forms the protonated azido ketone 2 , which goes through a rearrangement reaction with the alkyl group R, migrating over the C-N bond with expulsion of nitrogen.

    3 R 1 COO − + 3 R 2 COO − → R 1 −R 1 + R 1 −R 2 + R 2 −R 2 + 6 CO 2 + 6 e −. The reaction mechanism involves a two-stage radical process: electrochemical decarboxylation gives a radical intermediate, which combine to form a covalent bond. [2] As an example, electrolysis of acetic acid yields ethane and carbon dioxide: CH 3 COOH ...
