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…

Thiophene- and Selenophene Binding at a Pd3 Cluster Site.
TLDR
Thiophene or selenophene is accommodated stably at a Pd 3 site supported by a backside μ3 -cyclooctatetraene ligand through the face-capping μ 3 -coordination and forms a unique spiro-type Pd 5 cluster.
Bimodal coordination of fused arenes to a Pd3 cluster site.
TLDR
It is reported that a cyclooctatetraene-supported Pd3 cluster accommodates anthracene and tetracene in an oxidative π-addition manner, whereas triphenylene and fluoranthene are accommodated in a ρ-coordination manner.

TLDR
The rational synthesis of a 2D butterfly shaped Pd4 framework and 3D edge-sharing Pd6 tetrahedra by treatment of easily available organosilicon compounds with Pd(CNtBu)2 is reported, where the diphenylsilylene moiety serves as the key component to generate the butterfly structure of the Pd 4 clusters in 2.
