Abstract

A process for the preparation of diazo compounds, particularly diazoalkanes, is described in which a hydrazone is oxidized with an oxidizing agent, said oxidizing agent comprising an organic peracid, chloramine-T or N-chlorosuccinimide to a corresponding diazo compound, preferably in the presence of a base. The reaction may be catalyzed by an oxidation catalyst such as iodine.
