Organophosphides: A New Class of Luminophore Ligands for Copper(I) Carbene Based TADF Emitters and Photocatalysts

Angewandte Chemie International Edition, Volume 65, Issue 13, 23 March 2026.
Dimesitylphosphide as a heavier congener of established amide ligands for charge‐transfer copper(I) complexes leads to bathochromic shift of the emission by up to 3645 cm−1 into the orange‐red (solid, polymer films) and even NIR (solution). The thermally activated delayed fluorescence exhibits high dissymmetry factors of glum = 10−2 in polystyrene.

Visible‐Light Mediated Functionalization in Phe‐Containing Peptides Upon a Debenzylative Amination Process

Advanced Synthesis &Catalysis, Volume 368, Issue 6, 17 March 2026.
Selective late‐stage modification of N‐terminal phenylalanine short peptides is achived by visible‐light initiated reaction with N‐iodoimides in a debenzylation–amination process. This metal‐free method permits the incorporation of N‐containing heterocycles into the α‐position of the peptide backbone.

Building Molecules by a Self‐Replicator That Catalyzes Acyl Hydrazone Formation

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
A self‐replicator efficiently catalyzes the formation of acyl hydrazone bonds between a set of different substrates. In addition to previously reported (bond‐breaking) catalytic activity, this renders the self‐replicator highly promiscuous, which is a good starting point for Darwinian experiments en route to de‐novo life.

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Light‐Induced Reactions of Small‐Membered Cyclic Carbonyl Compounds

European Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
This review highlights recent advances in the synthesis and photochemical reactivity of cyclopropenone and cyclobutenedione. These compounds undergo photolysis upon direct excitation, and in some cases, through indirect excitation by photocatalysts. The resulting photogenerated species exhibit unique reactivity profiles that are strongly influenced by ...
