Carbonyl lock enables multi‐resonant organoboron framework with substantially enhanced spin‐flip and reduced emission bandwidth

open access: yesFlexMat, EarlyView.
Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

Clean and fast cross-coupling of aryl halides in one-pot

open access: yesBeilstein Journal of Organic Chemistry, 2014
Unsymmetrically coupled biaryls are synthesized in high yield starting from different aryl bromides and bis(pinacolato)diboron by carrying out the Miyaura borylation reaction followed by the Suzuki–Miyaura reaction in the same reaction pot over 1–2 mol %

Activation of Aryl Halides by Triplet–Triplet Annihilation Upconversion Enabling Coupling Processes Under an Open‐to‐Air Environment

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
Triplet–triplet annihilation upconversion (TTA‐UC) performed inside supramolecular viscoelastic gels enables efficient CC and C–heteroatom coupling reactions under green LED irradiation in open‐air conditions. The gel network restricts oxygen diffusion, preserves triplet states, and allows aryl halide activation through upconverted excited states ...

Rhodium(I)‐Catalyzed P(III)‐Directed C–H Alkylation of Biarylphosphines With Maleimides

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
A Rh(I)‐catalyzed P(III)‐directed ortho‐C–H bond alkylation of biarylphosphines with maleimides is disclosed. The reaction accommodates substituted alkenes, proceeds efficiently on gram scale, and consistently generates diastereomeric phosphines. NMR and mechanistic studies reveal that the stereochemical outcome arises from conformational restriction ...
