Ionic organic molecular cage-supported Pd nanoparticles for aqueous Suzuki-Miyaura coupling.

Spiroborate-linked organic molecular cages bearing bipyridine and phenanthroline ligands stabilize palladium nanoparticles whose dimensions are consistent with exocyclic growth. The cage-supported Pd nanoparticles act as efficient, recyclable catalysts for aqueous Suzuki-Miyaura coupling, affording high conversions under mild conditions while maintaining cage integrity, nanoparticle morphology, and activity over multiple cycles.
