Abstract
A series of mandelic acid derivatives was oxidised by molecular oxygen using cobalt(II) chloride as the catalyst. Benzaldehyde and/or benzoic acid derivatives were obtained in high selectivities, depending on the aromatic ring substitution. Different oxidation mechanisms are operating, depending on the mandelic acid substitution.
