Palladium(II) Complexes of a Neutral CCC-Tris(N-heterocyclic carbene) Pincer Ligand: Synthesis and Catalytic Applications

Treatment of tris-azolium precursor 1 with palladium acetate under thermal conditions provided a CCC-pincer palladium(II) complex (2) bearing three NHCs (one imidazolylidene and two triazolylidenes) and one iodide ligand. Further treatment of complex 2 with an excess of AgSbF6 generates tris(carbene) dicationic palladium complex 3 in which the iodine ligands are exchanged with SbF6 anions and the metal center is stabilized by one acetonitrile ligand. Complexes 2 and 3 were tested in several cross coupling reactions showing high conversions under low catalyst loadings and mild reaction conditions. Additionally, complexes 2 and 3 performed well in the hydrosilylation of terminal alkynes with good selectivity toward the E-isomer.

Oligoether substituted bis-NHC palladium and platinum complexes for aqueous Suzuki-Miyaura coupling and hydrosilylation

Abstract The synthesis of four oligo ethylene glycol substituted, bis-NHC palladium(II) and platinum(II) complexes is reported. Two of them were characterized by solid state structures. All complexes show excellent solubility in a variety of organic solvents and water. The palladium complexes were tested in the Suzuki-Miyaura coupling reaction and the platinum complexes in the hydrosilylation reaction of alkynes in aqueous solvent mixtures. All show a high catalytic activity at ppm level catalyst-loading under very mild reaction conditions.

Weakly-coordinated stable platinum nanocrystals

Stable platinum nanocrystals with small diameters (1.0-2.3 nm), that are stable for a long time, with narrow size distributions were easily and reproducibly prepared without any additional stabilizers in glycol, glycerol, the ionic liquids (ILs) 1-n-butyl-3-methyl-imidazolium tetrafluoroborate [BMIm][BF4] and N-butyl-N-trimethyl-ammonium bis(trifluoromethylsulfonyl)imide [N4111][NTf2] or diphenylmethane (CH2Ph2) by thermal, photolytic or microwave assisted decomposition of the organometallic precursor methylcyclopentadienyl-trimethylplatinum(iv), (MeCp)PtMe3. Decomposition of the easily dispensible, air and moisture stable organometallic Pt(iv) precursor (MeCp)PtMe3 leads to well defined, small, crystalline and longterm stable Pt-nanoparticle (Pt-NP) dispersions without any additional surface-capping ligands. The Pt-NP/IL dispersion was shown to be a highly active catalyst (TOF 96000 h-1 at 0.0125 mol% Pt and quantitative conversion) for the biphasic hydrosilylation of phenylacetylene with triethylsilane, to the distal and proximal products triethyl(2- and1-phenylvinyl)silane.

From Remote Alkenes to Linear Silanes or Allylsilanes depending on the Metal Center

The selective synthesis of linear silanes or allylsilanes from remote alkenes was explored. The cationic, unsaturated, 16-electron hydrido–silyl–RhIII complex was found to be an efficient catalyst for a tandem catalytic alkene isomerization–hyd
