Article Abstract

Herein, we present an efficient and feasible strategy for direct C-H fluorination and heteroarylation of oxindoles on the C-3 position having a C(sp)-H bond with quinoxalin-2(1)-ones based on a radical coupling reaction Selectfluor, a bifunctional reagent, as both the oxidant and fluorine source. This methodology provides a potential protocol to obtain 3-heteroaryl 3-fluorooxindoles in medium to excellent yields.

Ionization of alkanes to form radical cations activates their otherwise unreactive C-H bonds, facilitating important chemical processes such as hydrocarbon cracking. This work investigates the radical cation dissociation dynamics of hexane (CH) structural isomers by using femtosecond time-resolved mass spectrometry and quantum chemical calculations. All five isomers exhibit competition between the yields of fragment ions arising from direct C-C bond cleavage or dissociative rearrangement with hydrogen migration on dynamical time scales of ∼50-300 fs, suggesting that hydrogen migration in the metastable cations operates on such short time scales.

Allenes have gained prominence in transition metal-catalyzed C-H activation reactions due to their versatile reactivity. While C(sp)-H functionalization with allenes has been well explored, the functionalization of more challenging C(sp)-H bonds with allenes remains largely underexplored. Herein, we present a scalable Rh(III)-catalyzed strategy for the site-selective C(sp)-H dienylation of biologically relevant 8-methylquinolines employing allenyl carbinol acetates for accessing structurally diverse 1,3-dienes.

The dynamic structural evolution of heterogeneous catalysts is a ubiquitous phenomenon that has attracted a lot of interest. Catalyst reconstruction can occur after appropriate pretreatment, resulting in more efficient active catalysts, which is an attractive but challenging issue. Here, we reveal a CO activation strategy that controls the microenvironment of the Co sites in the high-silica Co-ZSM-5 catalyst (denoted as 0.

,-glycosides--glycosides characterized by two carbon substituents at the pseudo-anomeric position-constitute a structurally distinctive class of glycomimetics with growing relevance in natural products and drug discovery. These motifs appear in diverse bioactive compounds such as maitotoxin, nogalamycins, zaragozic acids and remdesivir, displaying antimicrobial, anti-inflammatory, and anticancer properties. The unique architectures of ,-glycosides expand the glycochemical space and hold promise for therapeutic development.

Efficiently activating inert C-H bonds while maintaining control over the selective pathways of complex chemical reactions involving high-energy species remains a highly challenging and as-yet unattained objective. Herein, we propose a novel concept called 'dynamic local free radical confinement-mediated mechanism' to efficiently achieve synergetic selective oxidation of toluene and hydrogen generation for the first time a CdS-CdInS semi-coherent heterojunction (CCS) under two-phase conditions. Surprisingly, the optimized CCS-2 exhibited amazing catalytic efficiency and long-term stability in gram-scale experiments and automatically separated the catalyst from the product.
