Selective Scrambling of Phenyl‐Stannanes: Main Group Catalysis With Aromatic Phosphorus Heterocycles

ChemistryEurope, Volume 4, Issue 4, April 2026.
Phosphinine–borane Lewis pairs catalyze the selective scrambling of phenylstannanes into SnPh4, H2, and elemental Sn. The reaction proceeds via transient SnH4 formation through reversible hydride and phenyl transfer steps within three interconnected cycles and enabled by an intrinsically weak P→B bond.

Rigid Ligand Environments at Beryllium, From Spectroscopic Probes to Small Molecule Activation

European Journal of Inorganic Chemistry, Volume 29, Issue 10, 1 April 2026.
Due to the high rigidity and definition of beryllium scorpionate complexes, they can be used to study metal‐pseudohalide and ‐carbon bonds in detail. Furthermore, these compounds can be used to activate small molecules and exhibit unprecedented transmetalation reactions. In beryllium scorpionate complexes, three of the four available coordination sites

FeCl3‐Catalyzed Synthesis of Ynones from Silylated Alkynes and Acetic Anhydride

ChemistryOpen, Volume 15, Issue 4, April 2026.
The synthesis of alkynones from silylated alkynes and acid chlorides, first reported by Birkhofer in 1963, remains a valuable transformation. However, its reliance on stoichiometric AlCl3 and corrosive reagents raises environmental and practical concerns. To address this, a greener protocol using catalytic FeCl3 and acetic anhydride is developed.

Organophosphide: Eine neue Klasse der Luminophorliganden für Kupfer(I)‐Carben‐basierte TADF‐Emitter und Photokatalysatoren

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.
Der Einsatz von Dimesitylphosphid als höheres Homolog der etablierten Amidoliganden für Charge‐Transfer‐Kupfer(I)‐Komplexe führt zu einer Rotverschiebung der Emission um 3645 cm–1 in den rot‐orangen Spektralbereich im Festkörper sowie in den NIR‐Bereich in Lösung. Die thermisch‐aktivierte verzögerte Fluoreszenz weist hohe Dissymmetriefaktoren von glum =

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.

Mild Generation of Highly Nucleophilic N‐Heterocyclic Carbene Boryl Anion From Neutral sp2–sp3 Diboron Reagents and Its Applications in Nucleophilic Borylation

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
A less hindered and highly nucleophilic N‐heterocyclic carbene (NHC) boryl anion is generated at room temperature by reacting sp2–sp3 diboron reagent (NHC)BH2Bpin with KOtBu. This highly reactive anion demonstrates broad reactivity with various electrophiles, including those traditionally considered inert, enabling their efficient borylation.
