Ruthenium‐Catalyzed Nitrile‐Acrylate Reductive Coupling by 2‐Propanol: Synthesis of Enantioenriched β‐Amino Esters

Angewandte Chemie, EarlyView.
The first nitrile reductive couplings beyond stoichiometric metals or metalloids are described. Using a ruthenium catalyst derived from RuHCl(CO)(PPh3)3 and Cy‐BIPHEP, 2‐propanol‐mediated reductive coupling of phenyl acrylate with aromatic or aliphatic nitriles delivers α,β‐unsaturated β‐amino esters.

Aza‐Büchner–Curtius–Schlotterbeck Reaction Enables Selective Construction of Quaternary Carbon Centers

Angewandte Chemie International Edition, EarlyView.
We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.

Deprotective Alkylation: A Platform for Alcohol‐to‐Amine Interconversion Using Nonafluoromesitylenesulfonamides

Angewandte Chemie International Edition, EarlyView.
The straightforward conversion of alcohols to tertiary or secondary amines employing Nms‐amides in a single operation is described. The transformation features broad functional group tolerance and high stereospecificity, underscoring its utility in the synthesis of isotope‐labeled pharmaceuticals.

Visible‐Light‐Induced Carbon–Hydrogen Phosphonylation of Conjugated Polymers via Electron Donor–Acceptor Complex Activation

Angewandte Chemie International Edition, Volume 65, Issue 40, 28 September 2026.
Electron donor–acceptor (EDA) complex activation enabled the efficient transformation of conjugated polymers. Compared with the small‐molecule model compound, the polymers reacted more efficiently, achieving quantitative conversion of PFO. This result demonstrates a new platform for incorporating conjugated polymers into EDA‐mediated photochemical ...

Bistable Switching of π‐Conjugation in a Dithienylethene‐Bridged Luminescent Trityl Diradicaloid

Angewandte Chemie International Edition, EarlyView.
Photoswitches that affect π‐conjugation offer a powerful strategy for external manipulation of luminescent diradicals. Dithienylethene‐linked persistent trityl diradicaloids, DTE‐TTM2 and F6‐DTE‐TTM2, exhibit bistable switching of their optical, electrochemical and magnetic properties.
