Summary: This study reveals that Aryl trifluoromethyl diazomethanes can be decomposed to form alpha-CF3 substituted carbene complexes under the effect of certain gold(I) complexes. The bonding situation of these complexes is thoroughly evaluated, showing the influence of the aryl substituent and Au in stabilizing the electrophilic carbene center. Reactivity studies confirm the typical carbene-type behavior for one of the complexes.

Summary: We synthesized and studied three new copper halide derivatives 2a-c, which are tetranuclear copper-iodide clusters consisting of a cubane-like {Cu4I4} motif and phosphine ligands P. They differ in the type of phosphines used as ligands: a monophosphine with a single pendant ester unit (2a), two pendant ester units (2b), and a diphosphine containing two esters in the linker (2c). The complexes displayed intense and long-lived photoluminescence in the orange region with PLQY values of 0.43-0.84 at room temperature, mainly associated with a (CC)-C-3 excited state with mixed (XMCT)-X-3 character.

Summary: Diphosphines with azobenzene scaffolds and their corresponding bis-gold chloride complexes were prepared and characterized through photophysical, spectroscopic, and X-ray diffraction studies. DFT calculations provided additional information on their electronic, structural, and spectroscopic properties. Comparative investigations were conducted on compounds with different substitution patterns to analyze the effects on structural and spectroscopic properties.

Summary: In this study, a carbone-transfer agent Ag-I complex of a bis(carbone) pincer ligand was synthesized, which eliminated the requirement for isolating the free ligand. The complex was efficiently used to transfer the ligand to other transition metals. This approach has potential for isolating metal complexes of carbone ligands, which has been challenging due to the reactivity and sensitivity of free carbones.

Summary: The reactivity of an Au(I) fluorido complex with alkynes was studied, leading to the formation of fluorovinyl species and hydrofluorination of alkynes. The catalytic ability of various Au(I) phosphine complexes in hydrofluorination reactions was compared, suggesting a reaction mechanism involving pre-coordination and nucleophilic addition. Mechanistic investigations confirmed the formation of a complex through nucleophilic addition, rather than the fluorido complex.

Summary: The research demonstrates the controlled access to (3+2) annulation by Au(I) catalysis of isoxazole-based nitrenoids with alkynyl thioethers, resulting in the synthesis of sulfenylated pyrroles and indoles as single regioisomers bearing useful functional groups and structural variety. This offers a new strategy for achieving varied heterocycle-substitution patterns by maintaining the same reaction pathways across different alkynes.

Summary: Gold(I) fluoride complexes with phosphine ligands were synthesized from their iodide precursors. Quantum-chemical comparisons between phosphine and N-heterocyclic carbene complexes yielded similar bonding situations. Experimental and calculated F-19 NMR chemical shifts showed good agreement, with phosphine complexes displaying approximately 40 ppm low-field shifts compared to NHC complexes. Reactivity studies of water-sensitive gold(I) fluoride complexes demonstrated metal substitution using trimethylsilyl reagents. The compounds were characterized using NMR and X-ray diffraction methods.

Summary: The syntheses and structures of a series of complexes based on the (CC)-C-?-chelated Au(III) unit were reported. The X-ray structures revealed varied dispositions determined by the different coordination modes of Ag(I) or Cu(I). The complexes showed bright photoluminescence in the solid state and in PMMA films, dominated by (IL)-I-3((CC)-C-?) transitions with indirect effects from the rest of the molecules.
