The choline- and peroxydisulfate-based environmentally benign biodegradable oxidizing task-specific ionic liquid (TSIL) choline peroxydisulfate (ChPS) was synthesized and characterized. This reagent enables a selective oxidation of alcohols to aldehydes/ketones in very good yields and short reaction time under solvent-free mild reaction conditions without overoxidation to acid.
