Bridging Coordination of Vinylarenes to Pd3‐ or Pd4 Cluster Sites

Though the M3‐ or M4 face of palladium clusters may serve as the active binding site of substrates, it has been difficult to elucidate their substrate binding modes in solution. Here, it was proved that a soluble Pd3‐ or Pd4 sheet cluster accommodates vinylarenes at its bridging coordination site in...

Summary:Though the M3‐ or M4 face of palladium clusters may serve as the active binding site of substrates, it has been difficult to elucidate their substrate binding modes in solution. Here, it was proved that a soluble Pd3‐ or Pd4 sheet cluster accommodates vinylarenes at its bridging coordination site in an unusual mode in palladium chemistry; that is, for the former, the coordination of the arene moiety precedes that of olefin moiety; for the latter, vinylarene coordinates to a distorted Pd4 sheet through oxidative π‐addition of its styrene moiety. Pd and arene coordination: It was proved that a Pd3‐ or Pd4 sheet cluster accommodates vinylarenes at its bridging coordination site in an unusual mode in palladium chemistry. The arene coordination precedes olefin coordination at the Pd3 site, and oxidative π‐addition takes place at the Pd4 site.
