Abstract
Aromatic compounds bearing oxidizable alkyl substituents, e.g., alkoxylated and/or hydroxylated such substrates, notably the phenolics/cresols, are selectively oxidized, e.g., into hydroxybenzaldehydes, by reacting same with appropriate oxidizing agents, in an aqueous reaction medium, in the presence of a catalytically effective amount of a solid, palladium-containing oxidation catalyst (optionally containing a cocatalytically effective amount of tin, germanium, tellurium and/or copper).
