FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway
Chemistry – A European Journal, EarlyView.Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence
Chemistry – A European Journal, EarlyView.Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Acid‐Catalyzed Rearrangement Reaction for Single‐Molecule Junction Formation
Chemistry – A European Journal, EarlyView.Hydrazobenzenes cannot form single‐molecule devices with gold electrodes in a nonpolar solvent, but with the addition of trifluoroacetic acid, robust single‐molecule junctions are created. Hydrazobenzenes likely undergo rearrangement reactions to form benzidines, which are then attached to gold contacts by dative NH2→Au interactions for junction ...

Chemistry – A European Journal, EarlyView.The synergic action of ascorbic acid and NHC^N ligands enables Au(I) oxidation with electron‐rich aryldiazonium salts. ABSTRACT The synergistic action of ascorbic acid and NHC^N ligands enables the challenging oxidation of Au(I) with electron‐rich aryldiazonium salts in the absence of a cocatalyst and/or irradiation. EPR, NMR, and x‐ray analyses reveal

Chinese Journal of Chemistry, EarlyView.Under copper(I) catalysis, pentafluoroethylated alkenes can undergo smooth defluorosilylation to generate novel polyfluorinated products. The reaction exhibits high levels of diastereoselectivities for obtaining multisubstituted allylsilanes with control of the double bond geometry.

CleanMat, EarlyView.Post‐synthetic bimetallic assembly constructs a 2D CoFe‐MOF composite. DFT confirms Fe→O→Co synergy optimizes the OER pathway (ΔGmax = 1.67 eV), leading to ultralow overpotential (290 mV) and robust stability. ABSTRACT Metal‐organic frameworks (MOFs) are promising oxygen evolution reaction (OER) electrocatalysts, yet their commercial viability is ...
