Sugar it up: Stabilization of the CrCl 2 active phase in a thin layer of an ionic liquid covalently grafted to mesoporous silica results in a highly selective catalyst for the dehydration of glucose to 5‐hydroxymethylfurfural (HMF) in an aqueous medium. Glucose dehydration in water by using the CrCl 2 ‐Im‐SBA‐15 catalyst leads to a 50 % HMF selectivity that can be further increased to up to 70 % by modifying the solvent system.
