Article Abstract

Recent years have seen increasing interest in uranyl(VI) photocatalysis. In this study, uranyl complexes were successfully synthesized from ligands - and UO(NO)·6HO under reflux conditions, yielding products - with yields ranging from 30% to 50%. The complexes were thoroughly characterized using NMR spectroscopy, single-crystal X-ray diffraction, and elemental analysis. The results indicate that complexes - possess a pentagonal bipyramidal geometry, whereas complex exhibits an octahedral structure. The photocatalytic properties of these novel complexes for sp C-H bond functionalization were explored. The results demonstrate that complex functions as an efficient photocatalyst for converting C-H bonds to C-C bonds via hydrogen atom transfer under blue light irradiation.

Nickel-Catalyzed Cross-Dehydrogenative Coupling of Aldehydes and Alkenes toward Skipped Enones.

The direct transformation of C-H bonds into C-C bonds via cross-dehydrogenative coupling (CDC) represents a powerful strategy in synthetic chemistry, enabling streamlined bond construction without the need for prefunctionalized substrates. While traditional CDC approaches rely on polar mechanisms and preactivation of one of the C-H partners, recent advances have introduced radical-based strategies that employ a hydrogen atom transfer (HAT) approach to access carbon-centered radicals from unactivated substrates. Herein, we report a nickel-catalyzed CDC reaction between aldehydes and alkenes for the synthesis of skipped enones, leveraging aryl radicals as intermolecular HAT agents.

Photofunctionalization of Light Alkanes by FeO/BCN at 12 °C.

The activation of methane and other gaseous hydrocarbons at low temperature remains a substantial challenge for the chemistry community. Here, we report an anaerobic photosystem based on crystalline borocarbonitride (BCN) supported Fe-O nanoclusters, which can selectively functionalize C-H bonds of methane, ethane, and higher alkanes to value-added organic chemicals at 12 °C. Scanning transmission electron microscopy and X-ray absorption spectroscopy corroborated the ultrafine FeOOH and FeO species in Fe-O clusters, which enhanced the interfacial charge transfer/separation of BCN as well as the chemisorption of methane.

Theoretical Study of Ru-Catalyzed Decarboxylative Heteroarylation of Aryl Carboxylic Acids.

The -di(2-pyridyl)arenes, featuring a unique structure, hold significant promise for applications in fluorescent probes, synthetic nanoparticle stabilizers, and chemical synthesis. The mechanism of Ru-catalyzed decarboxylation and heteroarylation reactions of aryl carboxylic acids to access -dipyridylarenes was elucidated using DFT calculations, which involved C-H bond activation, oxidative addition, reductive elimination, and decarboxylation processes to form -di(2-pyridyl)arenes. The rate-determining step of the reaction is the second reductive elimination step with an energy barrier of 27.

Carbon-hydrogen bond activation is a pillar of synthetic chemistry. While it is generally accepted that Pd is more facile than Ni in C-H activation catalysis, there are no experimental platforms available to directly compare the magnitude of C-H bond weakening between Ni and Pd prior to bond scission. This work presents the first direct measurements of C(sp)-H bond acidity (p) and bond dissociation free energy (BDFE) for a species containing a ligated alkane-palladium interaction (RCH···Pd), also known as an agostic interaction.

The photocatalytic oxidative dipolar [3 + 2] cycloaddition reaction is a promising green approach for producing pyrrolo[2,1-]isoquinolines. However, developing sustainable cycloaddition methods with heterogeneous photocatalysts is still in its infancy, largely owing to their low reactivity and photostability. Herein, we propose a charge-oxygen synergy strategy through a dual-engineered covalent organic framework (COF) by integrating π-spacers with donor-acceptor motifs to promote intermolecular cycloaddition.
