Summary: A simple cobalt complex, Co(phen)Cl₂, has been found to be a highly efficient and cost-effective precatalyst for various cross-coupling reactions involving aromatic and aliphatic organoaluminum reagents with aryl, heteroaryl, and alkyl bromides. New C(sp²)-C(sp²) and C(sp²)-C(sp³) bonds can be formed in good to excellent yields and high chemoselectivity under mild reaction conditions.

Summary: Cobalt-based catalysts have shown unique advantages in cross-coupling reactions, with higher catalytic activity and lower toxicity compared to palladium and nickel catalysts. A novel cobalt-catalyzed alkyl-alkyl cross-coupling reaction of hydrazone with alkyl halides has been developed under mild reaction conditions, using a PNP-type pincer ligand as an essential catalyst. Both aldehyde and ketone hydrazones are compatible with this reaction, producing a series of C(sp(3))-C(sp(3)) coupling products in moderate to good yields.

Summary: The molecular-level role of alkoxide salts as alternative additives in iron-catalyzed cross-coupling reactions is investigated. Spectroscopic studies reveal that alkoxides promote the formation of homoleptic organoferrates, providing a non-toxic alternative to N-methylpyrrolidone for accessing reactive intermediates.

Summary: An electron has been found to catalyze the cross-coupling reaction of organometallic compounds with aryl halides, which is more desirable for green and sustainable chemistry compared to transition metal catalysis. However, high temperature is required for this electron catalysis. We discovered that visible light photoirradiation can accelerate the electron-catalyzed reaction by using photoredox catalysis, enabling the reaction to proceed at room temperature. The supply of the electron catalyst through photoredox catalysis also expands the scope of aryl halides.

Summary: Here, the development of a copper-catalyzed C-(sp(3)) amination of unactivated secondary alkyl iodides mediated by diaryliodonium salts is described. The method involves the intermediacy of aryl radical species that undergo halogen atom transfer prior to interfacing with copper catalysts, enabling the formation of C-N bonds at sp(3)-hybridized carbons. The protocol is characterized by its mild reaction conditions, excellent regioselectivity, and wide substrate scope.

Summary: In this study, a method for achieving enantioselectivity in carbon-carbon cross-coupling reactions using iron-based catalysts is reported. By using chiral bisphosphine ligands, multicomponent cross-coupling reactions of vinyl boronates, (fluoro)-alkyl halides, and Grignard reagents can be achieved with up to 91:9 enantioselectivity, using commercially available and expensive iron salts.

Summary: This study demonstrates a nickel-catalyzed Negishi cross-coupling reaction for the synthesis of versatile organoboron products with high functional-group tolerance. The reaction allows for the coupling of unactivated tertiary alkyl electrophiles with boron-stabilized organozinc reagents. The importance of the Bpin group in accessing the quaternary carbon center is highlighted, and the practicality of the prepared quaternary organoboronates is showcased through their conversion to other useful compounds.

Summary: The authors report an on-cycle mechanism for CoCl2bpy2 catalyzed Negishi-type cross-coupling, elucidating the full catalytic cycle through multiple spectroscopic studies. Solvent and ligand were found to be crucial for generating catalytically active Co(I) species, with acetonitrile and bipyridine ligand resisting Co(I) disproportionation events. Combined investigations using Q-XAFS, EPR, IR, and DFT calculations provide comprehensive mechanistic insights into the structural information of the catalytic cobalt species and the entire Co(I)/Co(III) cycle. Additionally, the acetonitrile and bipyridine system can be extended to acylation, allylation, and benzylation reactions of aryl zinc reagents, demonstrating a broad substrate scope with a catalytic amount of Co salt. Overall, this work offers a fundamental mechanistic perspective for designing cobalt-catalyzed cross-coupling reactions.

Summary: A highly efficient heterogeneous copper(I)-catalyzed cross-coupling of trialkylsilylethynes with N-tosylhydrazones has been achieved using SBA-15-immobilized L-proline-Cu(I) complex as the catalyst and (LiOBu)-Bu-t as the base. The reaction occurs in dioxane at 90-110 degrees C and leads to the formation of C(sp)-C(sp(3)) bonds with moderate to high yields. The recyclable nature of the immobilized copper(I) complex allows for up to 12 repeated uses without significant loss of activity.

Summary: In this study, two novel sub-nanoporous COFs were synthesized and applied for the sieving of xenon/krypton for the first time. The as-prepared COFs demonstrated efficient adsorption and sieving of xenon/krypton due to their slightly larger pore sizes and good gamma-ray irradiation stability, showing great potential for practical applications in radioactive xenon/krypton separation. The multiple-site alkylation strategy proposed in this study provides a valuable approach for the construction and control of porous materials, especially sub-nanoporous adsorption materials.

Summary: This paper describes the preparation of diglycolamide ligands functionalized mesoporous silica matrix for the rapid and efficient separation of trivalent minor actinides (MAs) from high-level liquid waste. The modified silica materials showed strong affinity for MAs in highly acidic solutions and demonstrated high separation efficiency within a short time. The binding mechanism involved direct coordination of MAs to a tridentate oxygen binding site. Additionally, selective separation of americium from curium was achieved through oxidation of Am(III) by sodium persulfate. The outstanding sorption performance of these materials makes them promising for the immobilization of trivalent actinides and the separation of americium from curium.
