“…For decades, triangular metal clusters, especially those of group 10, have been widely studied due to their broad applications in synthesis and catalysis. − For example, previous experimental work by Li and co-workers has shown that the triangular tripalladium sandwich complex [Pd 3 (C 7 H 7 ) 2 (MeCN) 3 ](BF 4 ) 2 is an efficient catalyst for the cycloisomerization of 2-phenylethynylaniline to form 2-phenylindole . Recent experimental work also indicates that [Pd 3 Cl(PPh 2 ) 2 (PPh 3 ) 3 ] + [SbF 6 ] − cluster is an excellent catalyst for the Suzuki–Miyaura cross C–C coupling of a variety of aryl bromides and aryl boronic acid under ambient aerobic conditions .…”

Chemical bonding involving metal−metal (M−M) and metal−ligand (M−L) interactions provides an opportunity to tune the stabilities and catalytic properties of metal clusters. We report here the electronic and bonding properties of a series of trinuclear clusters [M 3 X 3 (PR 3 ) 3 ] + (M = Ni, Pd, Pt; X = F, Cl, Br, I; R = H) to explore the electronic effect on the adsorption and activation of H 2 and other small molecules. The chemical bonding model of M 3 is discussed in detail, and the formal +4/3 oxidation state of the metal element in the M 3 cluster is proposed. Metallic σ-aromaticity is also found in the trinuclear clusters. We have shown that the stability and the catalytic activity of the trinuclear clusters can be tuned by altering the energies and compositions of M−M and M−L chemical bonding orbitals. The performance of H 2 dissociative adsorption on these clusters can be explained by the orbital interactions. Relativistic effects also play a significant role in determining the activity of H 2 adsorption. This finding provides an example for controlling catalytic properties through tuning chemical bonding of metal clusters.

“…These have aroused great interest due to their wide range of applications. Their biological activity depends on the parent aldehyde or ketone [1][2]; also, palladium (II) complexes have shown to be catalytically active in the Heck and Suzuki-Miyaura cross-coupling reactions [3][4].…”

The purpose of this work is the design, synthesis and characterization of thiosemicarbazone ligands bearing a phenyl boronic acid functionality. The main interest is the synthesis of organopalladium compounds with the boronic acid included within the corresponding molecule. These could lead to further modification of the properties of the organometallic species applicable to the Suzuki-Miyaura reaction.The ligands were prepared by reaction of acetylphenylboronic acid with several thiosemicarbazides. The compounds were characterized by IR, 1 H and 31 P NMR spectroscopy.

Eine ungewöhnliche Struktur: Die neuartigen Titelverbindungen (siehe Schema) wurden synthetisiert und vollständig charakterisiert. Der vierkernige Komplex enthält einen sechseckigen Pd4Si3‐Kern mit einem zentralen Pd‐Atom, drei äußeren Pd‐Atomen und drei verbrückenden Si‐Atomen in einer Ebene, während der hantelförmige achtkernige Pd‐Komplex aus zwei durch einen Diphosphanliganden verbrückten Pd4Si3‐Gruppen besteht.
