Oxidative transformations of alcohols, oximes and cyclic acetals to carbonyl compounds proceed efficiently by pyridinium chlorochromate (PCC) under solvent-free conditions. The oxidation of aromatic and cinnamylic aldehydes to carboxylic acids, which does not occur by PCC in solution, is achieved satisfactorily in the absence of solvent.
