Phosphinoisocyanide Cyclisation: Generation of Azaphospholylidene (NPHC) Ligands

Angewandte Chemie International Edition, Accepted Article.
Phosphinoisocyanide complexes undergo facile [3+2] cycloaddition reactions with activated alkynes to afford the first azaphospholylidene complexes which are rare examples of N,P‐heterocyclic carbenes (NPHC). In addition to quantifying the donor/acceptor properties of this new class of carbene, their transmetallation reactions are also described.

Ruthenium Catalyzed ortho‐Arylation Reaction of Benzoic Acids with Arylthianthrenium Salts

Angewandte Chemie International Edition, Accepted Article.
Arylthianthrenium salts have become key intermediates for late‐stage functionalizations of drug‐like molecules. Ruthenium‐phosphine catalysts are now shown to enable their use as aryl sources in high‐yielding ortho‐C–H arylations of benzoic acids. The arylthianthrenium salts are converted chemo‐selectively, leaving aryl halides and boronates untouched.

Machine learning‐augmented molecular dynamics simulations (MD) reveal insights into the disconnect between affinity and activation of ZTP riboswitch ligands

Angewandte Chemie International Edition, Accepted Article.
The challenge of targeting RNA with small molecules necessitates a better understanding of RNA‐ligand interaction mechanisms. However, the dynamic nature of nucleic acids, their ligand‐induced stabilization, and how conformational changes influence gene expression pose significant difficulties for experimental investigation.

Reactivity of Pnictaalumenes towards 1,3‐Dipole Molecules

Angewandte Chemie International Edition, Accepted Article.
Alkynes undergo 1,3‐dipolar cyclisation reactions with organic azides giving 1,2,3‐triazoles. Pnictaalumenes RPn=AlRˈ are the isoelectronic congeners of alkynes, hence a similar reactivity towards 1,3‐dipole molecules is expected. Herein, we report the reactions of DippTerPn=AlCp* (DippTer = 2,6‑(2,6‐iPr2C6H3)‐C6H3, Cp* = [Me5C5]−, Pn = P, As) towards ...
