Bridging Coordination of Vinylarenes to Pd3‐ or Pd4 Cluster Sites

“…[3,4] However,c oordination behavior of vinylarenes to the bridging sites of Pd clusters has been virtually unexplored.O ur group recently developed organo-Pd 3 or Pd 4 clusters, which enable binding of substrates at their reactive Pd 3 -o rP d 4 clusters ites. [11][12][13][14][15][16][17][18] Notably,t he arene-Pd 3 -COT clusters undergo areneexchange reactions under gentle heating conditions, [5,6] althoughk nown m 3 -arene M 3 clusterso fo ther transition metals are inert towarda rene-exchange.T he half-sandwich Pd 4 sheet cluster supported by ab ackside COT ligand (Scheme 1) also providesaunique Pd 4 clusters ite, which accommodates naph-thalenei na nu nusual oxidative p-addition mode.
