Photofunctional Platinum Complexes Featuring N-heterocyclic Carbene-Based Pincer Ligands

open access: yes, 2015
Photoactive platinum complexes of stoichiometry [Pt(RCCCR)L]0/+ (R=Me, nBu and L=[BOND]CN, [BOND]C≡CPh, [BOND]N≡CCH3, [BOND]Py, [BOND]CO) featuring pincer-type bis N-heterocyclic carbene (NHC) ligands (RCCCR) were synthesized. Organometallic syntheses of

Tethered N‑Heterocyclic Carbene-Carboranyl Silver Complexes for Cancer Therapy [PDF]

open access: yes, 2019
Silver complexes of tethered N-heterocyclic carbene-carboranyl ligands have been prepared and fully characterized. The first example of silver bonded directly to the cage of o-carborane has been identified in the solid state.

Benzylic C−H acylation by cooperative NHC and photoredox catalysis

open access: yesNature Communications, 2021
Direct acylation of sp3 C−H bonds in complex organic molecules is not well established compared to that of sp2 C−H bonds. Here, the authors report the combination of N-heterocyclic carbene (NHC) and photoredox catalysis for the direct and site-selective ...

Catalytic Hydrogenations with Cationic Heteroleptic Copper(I)/N-Heterocyclic Carbene Complexes

open access: yes, 2019
A new heteroleptic cationic copper(I) complex bearing two N-heterocyclic carbene (NHC) ligands has been prepared. In situ, a Cu–O-bond can be generated which enables the complex to catalytically activate H2.

Catalytic Hydrogenation of α,β-Unsaturated Carboxylic Acid Derivatives Using copper(I)/N-Heterocyclic Carbene Complexes

open access: yes, 2018
A simple and air-stable copper(I)/N-heterocyclic carbene complex enables the catalytic hydrogenation of hitherto unreactive enoates and enamides employing H2 as terminal reducing agent.

Investigations into the Antibacterial Activity of the Silver-Based Antibiotic Drug Candidate SBC3

open access: yesAntibiotics, 2012
The synthesis of N-heterocyclic carbene (NHC) silver(I) acetate complexes with varying lipophilic benzyl-substituents at the 1 and 3 positions starting from 4,5-diphenylimidazole, opened a new class of antibiotic drug candidates.

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

open access: yesAngewandte Chemie International Edition, EarlyView.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness
