Angewandte Chemie, EarlyView.B─N Lewis pair fusion of N,N‐dipyridyldihydrophenazine and its benzofused homologs results in steric constraints that enforce a bent structure in both the ground and excited states, reduces the antiaromatic character of the central dihydropyrazine heterocycle and promotes a quinoidal resonance structure, bathochromically shifts the absorption and ...

Angewandte Chemie, EarlyView.Human H ferritin (HuHf) is a nanocarrier for anticancer metal drugs. By cryo‐EM, a 1.51 Å structure of its adduct with Au(NHC)Cl was solved, showing a novel tetranuclear gold(I) cluster bound to Cys90 and Cys102. Short inter‐metal distances indicate aurophilic interactions.

Angewandte Chemie, EarlyView.Stable imino‐substituted Au(III) carbenes are easily and efficiently prepared by trapping the transient (N^C^C)Au←:CH(dmp)+ carbene with nitriles. The corresponding free species are readily generated and display dual carbene / nitrile‐ylide reactivities. The diazo decomposition, nitrile insertion, and carbene transfer can be combined in three‐component

Angewandte Chemie, EarlyView.A monomeric alumylene stabilized by two donor ligands (phosphine and NHC) has been successfully synthesized. This alumylene complex exhibits an enhanced nucleophilic character and a preserved ambiphilic reactivity compared to the monoligated complex. As a consequence, its oxidation by N2O proceeds even at −90 °C, allowing the synthesis of an acceptor ...

Functional Ambidexterity of an Ancient Nucleic Acid‐Binding Domain
Angewandte Chemie, EarlyView.The (HhH)2‐Fold is an ancient and ubiquitous nucleic acid‐binding domain. We demonstrate that this domain, which interacts with the minor groove of dsDNA, is functionally ambidextrous – that it can bind to dsDNA of either chirality. Moreover, binding of both chiral forms of dsDNA is mediated by an overlapping binding surface.
