Evidence for Suzuki-Miyaura cross-couplings catalyzed by ligated Pd-clusters: from cradle to grave.

Pd clusters offer unique selectivity and exploitable reactivity in catalysis. Understanding the behavior of Pd clusters is thus critical for catalysis, applied synthetic organic chemistry and greener outcomes for precious Pd. The Pd cluster, [Pd(μ-Cl)(μ-PPh)(PPh)][Cl] (denoted as PdCl), which exhibits distinctive reactivity, was synthesized and immobilized on a phosphine-functionalized polystyrene resin (denoted as immob-PdCl).
