Choline peroxydisulfate (ChPS)
Choline peroxydisulfate is a environmentally benign, biodegradable ioniq liquid, that can be synthesized from choline chloride and potassium peroxydisulfate in acetone in 24 h at room temperature. ChPS is a versatile, thermally stable, non-volatile, task-specific ioniq liquid, that can be used for mild oxidations.
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.
