Photosensitizer-Free Visible-Light-Mediated Gold-Catalyzed 1,2-Difunctionalization of Alkynes.
With a P,N-bidentate ligand, a stable aRYl gold(III) species was obtained, which constitutes the first direct experimental evidence for the commonly postulated direct oxidative addition of an aryl diazonium salt to a pyridine phosphine gold(I) complex. Expand
New and Easily Accessible Nitrogen Acyclic Gold(I) Carbenes: Structure and Application in the Gold‐Catalyzed Phenol Synthesis as well as the Hydration of Alkynes
A series of gold(I) isonitrile complexes were prepared and converted to the corresponding diaminocarbene gold(I) complexes by reactions with primary and symmetrical secondary amines. Twelve crystalExpand
Development of Platinum(II) and -(IV) CNC Pincer Complexes and Their Application in a Hydrovinylation Reaction
A series of new, dicationic platinum(II) CNC pincer complexes were prepared and characterized by NMR and X-ray diffraction analysis. Oxidative addition of methyl iodide and iodine yielded the mostlyExpand
Homogeneous and heterogenised new gold C-scorpionate complexes as catalysts for cyclohexane oxidation
Gold(III) complexes of type [AuCl2{η2-RC(R′pz)3}]Cl [R = R′ = H (1), R = CH2OH, R′ = H (2) and R = H, R′ = 3,5-Me2 (3), pz = pyrazol-1-yl] were supported on carbon materials (activated carbon, carbonExpand
The first catalytic synthesis of an acrylate from CO2 and an alkene-a rational approach.
A homogeneous catalyst based on nickel is described that permits the catalytic synthesis of the industrially highly relevant acrylate sodium acRYlate from CO(2), ethylene, and a base, as demonstrated by a turnover number of greater than 10 with respect to the metal. Expand
Synthesis and Structures of Copper(I) Complexes with Phosphino-Functionalized N-Heterocyclic Carbenes (NHCP) and Bis-N-Heterocyclic Carbenes (Bis-NHC)
New copper(I) complexes bearing N-phosphino- and N-phosphinomethyl-functionalized NHC ligands (NHCP systems) were synthesized and fully characterized. Using halide-containing copper(I) precursors,Expand
Diastereoselective Synthesis of Functionalized Diketopiperazines through Post-transformational Reactions.
A diversity-oriented access to diastereoselective arylidene 2,5-diketopiperazines is elaborated via a sequential Ugi post-transformation involving catalytic cyclization and oxidative Heck reactionExpand
Synthesis and optical properties of diaza- and tetraazatetracenes.
1,2,3,4-tetrafluoro-6,11-bis((triisopropylsilyl)ethynyl)benzo[b]phenazine was synthesized, which is the first reported fluorinated diazatetracene and single-crystal X-ray analysis of this compound is reported. Expand
Ir-catalysed asymmetric allylic substitutions with cyclometalated (phosphoramidite)Ir complexes--resting states, catalytically active (pi-allyl)Ir complexes and computational exploration.
A novel, one-pot procedure for the preparation of (pi- allyl)Ir complexes was developed, and these complexes were characterised by X-ray crystal structure analyses and spectral data, and they are fully active catalysts of the allylic substitution reaction. Expand
