Dynamic Supramolecular [(Salen)CrCl] Complexes as Efficient Catalysts for Ring Opening of Epoxides

This is the authors' abstract. We don't add key points for this paper.

Dynamic clamp: Hydrogen-bond- assembled supramolecular [(salen)CrIIICl] 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.
