Synthesis and Solution Isomerization of Water-Soluble Au9 Nanoclusters Prepared by Nuclearity Conversion of [Au11(PPh3)8Cl2]Cl

Water-soluble gold nanoclusters (AuNCs) are popular in biomedical applications such as bioimaging, labelling, drug delivery, and biosensing. Despite their widespread applications, the synthesis of water-soluble phosphine-capped AuNCs is not as...

Homogeneous hydroformylation of long chain alkenes catalyzed by water soluble phosphine rhodium complex in CH3OH and efficient catalyst cycling

Hydroformylation of long-chain alkenes proceeded homogeneously in methanol efficiently. The catalyst could be separated heterogeneously when methanol was removed and recycled for four times without obvious loss in catalytic performance and rhodium.

Isolation, Optical Properties and Core Structure of a Water-soluble, Phosphine-stabilized [Au9]3+ Cluster

A water-soluble, crystalline Au9 cluster compound stabilized with sodium (m-sulfonatophenyl) diphenylphosphine (TPPMSNa) was obtained during the NaBH4 reduction of [Au(TPPMSNa)Cl] H2O in ethanol. Characterization by optical extinction spectroscopy, singlecrystal X-ray diffraction in combination with energy dispersive X-ray diffraction led to the preliminary formula Na(8-x)[Au9(TPPMS)8]Cl(3-x) nH2O (0 ≤ x ≤ 3, n ≈ 16) with the cluster core in crown conformation. 31P{1H} nuclear magnetic resonance spectroscopy revealed one singlet at 57:3 ppm. This is the first example where gold clusters stabilized by TPPMSNa formed crystals which where suitable for core structure determination

Lower- and upper-rim-modified derivatives of 1,3,5-triaza-7-phosphaadamantane: Coordination chemistry and applications in catalytic reactions in water

In this article, a brief review of the recent functionalizations of the cage-like water-soluble phosphine 1,3,5-triaza-7-phosphaadamantane (PTA), involving N-quaternization (lower rim) and introduction of a side arm in C-6 position (upper rim) will be presented, highlighting selected examples in their use as ligands for ruthenium(II), iridium(I), and rhodium(I) moieties together with applications of the related complexes in homogeneous catalysis.
