Dynamic clamp: Hydrogen‐bond‐ assembled supramolecular [(salen)Cr III Cl] complexes display higher catalytic activity towards the ring opening of epoxides with trimethylsilyl azide compared to the prototype Jacobsen's Cr catalyst. Introduction of an alkyl strap to each assembling component leads to even higher catalytic activity, which is probably due to the formation of more of the supramolecular cyclic dimer.
