Remarkable Acceleration of Diels–Alder Reactions in a Self-Assembled Coordination Cage

Abstract: Self-assembled coordination cage 1 was found to accelerate Diels–Alder reactions in an aqueous media: e.g., 113-fold acceleration was observed in the reaction of isoprene with naphthoquinone.

“…[45] Die Fujita und Mitarbeiter setzten den wasserlöslichen metallorganischen Käfig 1 bei Raumtemperatur zur Beschleunigung der Diels-Alder-Reaktion von 1,4-Naphthochinon mit Cyclohexadien ein. [47] In wässriger Lösung nimmt der hydrophobe Hohlraum von 1 zwei Moleküle jedes Substrats auf, die anschließend rasch (ca. 21-mal schneller) und quantitativ zu 11 reagieren (Schema 2).…”

“…The earliest examples of altered chemical activity within supramolecular coordination compounds come from Fujita and coworkers, in which they employed their palladium-vertexed octahedra (Fig. 16) in the Diels-Alder cycloaddition of isoprene with naphthoquinone [26], accelerating this bimolecular addition 113-fold. The basis of the rate acceleration by this host is an increased effective molarity within the assembly cavity.…”
