Article Abstract

Rh(III)-catalyzed oxidative [3+2] annulation between arylboron reagents and azabicyclic olefins is presented. This system offers an effective example of transmetalation-promoted C-H activation using easily available arylboron reagents, which provides a series of -fused dihydrocarbazoles both and functionalization of the arylboron reagents. Importantly, this annulation reaction circumvents the reliance on a directing group in the arene ring.

To explore arylboron transmetalation at manganese(I), reactions of 4-fluorophenylborates with pentacarbonylmanganese(I) hexafluorophosphate cation (CO)Mn(MeCN)(PF) were evaluated for the formation of 4-fluorophenylmanganese(I) pentacarbonyl (CO)Mn(4-F-CH). The optimal reagent was neopentylglycol 4-fluorophenylboronic ester activated with -butyllithium, which reacted with (CO)Mn(MeCN)(PF) to give (CO)Mn(4-F-CH) in 58% yield. These conditions were extrapolated to reactions involving other neopentylglycol esters to yield a scope of seven (CO)Mn(I)-aryls with varied substitutions on the aryl ring.

(Vinyl triflimide)benziodolium Salts: Palladium-Catalyzed Cascade Reactions toward Unsymmetrical Benzils.

Org Lett

June 2025

Shanghai Key Laboratory of Functional Materials Chemistry, Key Laboratory for Advanced Materials and Institute of Fine Chemicals, School of Chemistry and Molecular Engineering, East China University of Science and Technology, Shanghai 200237, China.

(Vinyl triflimide)benziodolium salts were developed as new hypervalent iodine reagents. A cascade of diarylation/oxidation reactions with the benziodolium salts was accomplished in the presence of palladium catalysts. The reaction exhibits extensive compatibility with readily available arylboronic acids, giving a diverse array of benzyl derivatives in good yields.

Endoplasmic reticulum (ER)-targeted ratiometric fluorescent probe for visualization of ER-phagy induced by ONOO and NIR imaging in mice with drug-induced liver injury.

Drug-induced liver injury (DILI) remains a persistent and unavoidable challenge in biomedicine, significantly impacting preclinical drug development and early clinical trials. The liver, as the primary site for endogenous antioxidant production, is particularly sensitive to acute damage mediated by reactive oxygen species (ROS) and reactive nitrogen species (RNS). The ratiometric and near-infrared (NIR) detection of peroxynitrite (ONOO), as potential biomarker for DILI, is crucial for enhancing the imaging effectiveness of liver damage.

The origin of the - and -to-fluorine site-selectivity in the C(sp)-H borylation of fluorinated arenes with BPin and HBPin promoted by pyridine(dicarbene)cobalt catalysts has been investigated. generation of the cobalt(I)-boryl complex and treatment with three representative fluoroarenes established -selective C(sp)-H oxidative addition to form predominantly the isomers of the corresponding cobalt(I)-aryl complexes. Attempts to observe or isolate the four-coordinate cobalt(I)-boryl complex yielded the cobalt-hydride dimer, , borohydride , or diboryl hydride, depending on the amounts of BPin and HBPin present.
