Abstract
Derivatization of (NHC)M-Cl (M = Ag, Au) with selected sulfur donors from the family of dialkyldithiophosphates and bis(2-mercapto-1-methylimidazolyl)borate ligands gave a series of heteroleptic mononuclear complexes. In single-crystal X-ray diffraction analysis, Ag(I) complexes adopted a trigonal planar geometry, while Au(I) complexes are near-linear. TD-DFT and hole-electron analyses of the selected complexes gave insight into the electronic features of the metal complexes. In vitro cellular tests were conducted on the human cancerous breast cell line MCF-7 using 2 and 8. The antibacterial activities of complexes 1, 2, 3, 7, 8, and IPr-Ag-Cl were also screened against Gram-positive (Staphylococcus aureus PTCC 1112) and Gram-negative (Escherichia coli PTCC 1330) bacteria. Antityrosinase and hemolytic effects of the selected compounds were also determined.

Abstract
14 new gold(I) NHC complexes of the type [AuX(iPr2-bimy)] (iPr2-bimy = 1,3-diisopropylbenzimidazolin-2-ylidene) have been prepared and fully characterized. These complexes and their reported analogues were used to systematically compare and rank the donating abilities of overall 34 anionic X-type donors by 13C NMR spectroscopy. Specifically, the carbene chemical shift of the iPr2-bimy ligand was found to be responsive to the ligand X spanning an overall range Δδ > 37 ppm between the strongest and weakest donor in this study.

Abstract
A series of mixed bis-NHC rhodium(I) complexes of type RhCl(η2-olefin)(NHC)(NHC’) have been synthesized by a stepwise reaction of [Rh(μ-Cl)(η2-olefin)2]2 with two different NHCs (NHC = N-heterocyclic carbene), in which the steric hindrance of both NHC ligands and the η2-olefin is critical. Similarly, new mixed coumarin-functionalized bis-NHC rhodium complexes have been prepared by a reaction of mono NHC complexes of type RhCl(NHC-coumarin)(η2,η2-cod) with the corresponding azolium salt in the presence of an external base. Both synthetic procedures proceed selectively and allow the preparation of mixed bis-NHC rhodium complexes in good yields.

Abstract
![]()
Acyclic diamino carbenes
(ADCs) are interesting alternatives to
their more widely studied N-heterocyclic carbene counterparts, particularly
due to their greater synthetic accessibility and properties such as
increased sigma donation and structural flexibility. ADC gold complexes
are typically obtained through the reaction of equimolar amounts of
primary/secondary amines on gold-coordinated isocyanide ligands. As
such, the reaction of diamine nucleophiles to isocyanide gold complexes
was expected to lead to bis-ADC gold compounds with potential applications
in catalysis or as novel precursors for gold nanomaterials. However,
the reaction of primary diamines with two equivalents of isocyanide
gold chlorides resulted in only one of the amine groups reacting with
the isocyanide carbon. The resulting ADC gold complexes bearing free
amines dimerized via coordination of the amine to the partner gold
atom, resulting in cyclic, dimeric gold complexes. In contrast, when
secondary diamines were used, both amines reacted with an isocyanide
carbon, leading to the expected bis-ADC gold complexes. Density functional
theory calculations were performed to elucidate the differences in
the reactivities between primary and secondary diamines. It was found
that the primary amines were associated with higher reaction barriers
than the secondary amines and hence slower reaction rates, with the
formation of the second carbenes in the bis-ADC compounds being inhibitingly
slow. It was also found that diamines have a unique reactivity due
to the second amine serving as an internal proton shuttle. Reactions between primary diamines with
a gold-coordinated
isocyanide complex afforded unexpected cyclic dimeric gold complexes
instead of bis-acyclic diamino carbene gold complexes, which were
obtained when using secondary diamines. DFT calculations revealed
that primary amines react slower in the carbene-forming reaction,
with the barrier of the second carbene formation ultimately resulting
in this interesting selectivity.
