[4-Iodo-3-(isopropylcarbamoyl)phenoxy]acetic acid is a highly reactive and easily separable catalyst for the oxidative cleavage of tetrahydrofuran-2-methanols to γ-lactones in the presence of Oxone as the terminal oxidant.The catalyst and product were easily separated by only liquid-liquid separation without chromatography.
