The Flexibility of Tetra(N‐Heterocyclic Carbene) Ligands Controls the Nuclearity and Geometry of Polynuclear MI‒NHC Assemblies

Angewandte Chemie International Edition, Accepted Article.
A series of tetrakisimidazolium salts bearing two di(phenylimidazolium)amine groups linked by differently substituted anthracenes has been prepared. These are H4‐1a(PF6)4 (anthracene bridge), H4‐1b(PF6)4 (phenyl‐anthracene‐phenyl bridge), H4‐1c(PF6)4 (anthracene‐phenyl bridge) and H4‐1d(PF6)4 (anthracene‐phenyl‐anthracene bridge).

Understanding and Tuning Singlet–Triplet (S1–T1) Energy Gaps in Planar Organic Chromophores

Angewandte Chemie International Edition, EarlyView.
A new framework for tuning singlet–triplet (S1–T1) gaps based on electrostatic interactions of the transition density is developed. Three widely applicable design rules for maximizing the singlet–triplet gap are derived: minimizing the number of electrons, localizing the excitation, and optimizing through‐space interactions.

Structural Insight into a Human H Ferritin@Gold‐Monocarbene Adduct: Aurophilicity Revealed in a Biological Context

Angewandte Chemie International Edition, Accepted Article.
Human H ferritin (HuHf) has excellent potential as a nanocarrier for the selective delivery of anticancer metal‐based drugs to tumour cells. Here, we addressed the interaction of the gold monocarbene compound Au(NHC)Cl with HuHf by electrospray ionization‐mass spectrometry (ESI‐MS) measurements, which provide the metalation state of the protein ...

β‐Quaternary α‐Amino Acids via Iridium‐Catalyzed Branched and Enantioselective Hydroalkylation of 1,1‐Disubstituted Styrenes

Angewandte Chemie International Edition, Accepted Article.
A cationic Ir(I)‐complex modified with the chiral diphosphine DM‐SEGPHOS mediates the hydroalkylation of diverse α‐methyl styrenes with N‐aryl glycine derivatives. The processes occur with complete branched selectivity and high enantioselectivity. Styrenes possessing higher α‐alkyl substituents also participate to provide the targets with moderate to ...

A Joyful Journey: Tungsten(VI) and Tungsten(V) Fluorides Meet N‐Heterocyclic Carbenes and Cyclic (Alkyl)(amino)carbenes

Angewandte Chemie International Edition, Accepted Article.
The first complexation of tungsten(VI) fluoride with N‐heterocyclic carbenes (NHCs) and a cyclic (alkyl)(amino) carbene (cAACMe) is reported, which led to the complexes [(NHC)WF6] (NHC = IiPrMe, 1; BIiPr, 2; IMes, 3; IDipp, 4; and SIDipp, 5) and [(cAACMe)WF₆] 6. Solid‐state structural analysis reveals distorted mono‐capped trigonal prismatic geometries

Functional Ambidexterity of an Ancient Nucleic Acid‐Binding Domain

Angewandte Chemie International Edition, Accepted Article.
The helix‐hairpin‐helix (HhH) motif is an ancient and ubiquitous nucleic acid‐binding element that has emerged as a model system for studying the evolution of dsDNA‐binding domains from simple peptides that phase separate with RNA. We analyzed the entire putative evolutionary trajectory of the HhH motif – from a flexible peptide to a folded domain ...
