Sommelet reaction

The Sommelet reaction is an organic reaction in which a benzyl halide is converted to an aldehyde by action of hexamine and water.[1][2][3]

The reaction is formally an oxidation of the carbon. In the related Kröhnke aldehyde synthesis,[4][5] the oxidizing reagent is a combination of pyridine and p-nitrosodimethylaniline.

The reaction has proved useful for the preparation of aldehydes from amines and halides. Various types of aromatic, heterocyclic, some aliphatic aldehydes and amines have been prepared.
