[3]Rotaxane-Based Dinuclear Palladium Catalysts for Ring-closure Mizoroki–Heck Reaction

[3]Rotaxane containing two Pd centers in the cyclic compounds catalyzes a Mizoroki–Heck reaction of substrates with two iodophenyl groups with bisacrylate. Formation of the cyclic products is enhanced by the rotaxane catalyst more smoothly than Pd(OAc)2.
