Transient self‐organization of Cr complexes into binuclear structures is the key to the selective dehydration of glucose to 5‐hydroxymethylfurfural by chromium chlorides in ionic liquids. In their Full Paper on page 5281 ff. , E. J. M. Hensen et al. demonstrate that the mechanism of the selective glucose transformations does not depend on the oxidation state of the chromium catalyst. Because of its enhanced Lewis acidity, CrCl 3 ⋅ x H 2 O ( x =0 or 6) shows higher activity and selectivity to HMF compared to CrCl 2 .
