The first tris(mercaptoimidazolyl)borate complexes of gold, Au(Tm tBu) and (TmtBu)Au(PPh3), have been prepared and structurally characterized. Together with their copper and silver analogues M(TmtBu) and (Tmsup

Combining phase-dependent photoluminescence (PL) measurements and quantum chemical calculations is a powerful approach to help understand the influence of the molecular surroundings on the PL properties. Herein, a phosphine functionalized amidinate was used to synthesize a recently presented bimetallic gold complex, featuring an unusual charge separation. The latter was subsequently used as metalloligand to yield heterotetrametallic complexes with an Au-M-M-Au “molecular wire” arrangement (M=Cu, Ag, Au) featuring metallophilic interactions. All compounds show bright phosphorescence in the solid state, also at ambient temperature. The effect of the molecular environment on the PL was studied in detail for these tetrametallic complexes by comparative measurements in solution, in the solid state and in the gas phase and contrasted to time-dependent density functional theory computations.
Organometallic complexes for non-linear optics XII. Syntheses and second-order susceptibilities of (neomenthyldiphenylphosphine) gold σ-arylacetylides: X-ray crystal structures of Au( C≡CPh) (nmdpp) and Au((E)-4,4′-C≡CC6H4CH=CHC6H4NO2)(nmdpp)

The series of complexes Au(C≡CR)(nmdpp) (R = Ph (2), 4-C6H4NO2 (3), 4,4′-C6H4C6H4NO2 (4), (Ε)-4,4′-C6H4CH=CHC6H4NO2 (5), (Ζ)-4,4′-C6H4CH=CHC6H4NO2 (6), 4,4′-C6H4C≡CC6H4NO2 (7), 4,4′-C6H4N=CHC6H4NO2 (8); nmdpp = (+)-neomenthyldiphenylphosphine) has been synthesized by reaction of AuCl(nmdpp) with the corresponding acetylene and methoxide in the presence of trace amounts of a phosphine oxide, and complexes 2 and 5 have been structurally characterized. Complexes 2-8 and analogous (triphenylphosphine)gold acetylides and precursor (phosphine)gold chlorides have been examined for their second-order bulk susceptibilities χ(2) by the Kurtz powder technique, with the largest response (ca. 2 × urea) being that from 3.

The modular synthesis of Au(I)/Ru(II) decorated mono- and heterobimetallic complexes with π-conjugated [2.2]paracyclophane is described. [2.2]Paracyclophane serves as a rigid spacer which holds the metal centers in precise spatial orientations and allows
Gold(I)-Catalysed Hydroarylation of Lactam-Derived Enynes as an Entry to Tetrahydrobenzo[g]quinolines

The gold(I)-catalysed cyclization of N-tosyl-protected 5-benzyl-6-((trimethylsilyl)ethynyl)-1,2,3,4-tetrahydropyridines, prepared by the Sonogashira coupling of lactam-derived enol triflates, provides tetrahydrobenzo[g]quinolines whose skeleton represents a recurrent motif in natural compounds. The Au(I)-catalysed reaction is carried out with (C6F5)3PAuCl/AgNTf2 as the catalyst system and proceeds via a 6-exo-dig cyclization to form an exocyclic double bond, which eventually isomerises to the aromatic tetrahydrobenzo[g]quinoline. The mode of cyclization is discussed and supported by DFT calculations.
