This paper describes the design and synthesis of two new fluorous crown ethers (named 1 and 2) carrying sugar molecules modified with multivalent Bfp. Subsequently, we investigated their partition ratios in biphasic systems using FC 72 and several organic solvents. Then, we assessed the activities of 1 or 2 in an FC 72/acetonitrile biphasic system via the acetoxylation reaction using 2-(bromomethyl)naphthalene and potassium acetate, followed by examinations of their recyclability in a two-layer system based on their immobilization in an FC 72 solvent during the acetoxylation reactions.
