Abstract ：
Alternating current electrolysis has emerged as a promising technique for addressing challenging redox reactions that are otherwise difficult or impossible for direct current electrolysis. Under mild and transition-metal-free reaction conditions, a general electrochemical denitrative cyclization of nitroarenes was developed to access various cyclic sulfone-containing derivatives of biological significance. The key to success lies in the facile manipulation of multiple redox events upon rapid alternating polarity switching to enhance the selectivity and efficiency.

Abstract ：
In most Suzuki-Miyaura carbon-carbon cross-coupling reactions, the borabicyclo[3.3.1]nonane scaffold (9-BBN) only serves as an auxiliary facilitating the transmetalation step and thus is transformed into by-products. There are rare examples where the 9-BBN derivatives serve as the potentially diverse C8 building blocks in cross-coupling reactions. Herein, we report a cobalt-catalyzed migratory carbon- carbon cross-coupling reaction of the in situ formed 9-BBN ate complexes to afford diverse aryl- and alkyl-functionalized cyclooctenes. Preliminary mechanistic studies suggest the oxidation-induced cis- bicyclo[3.3.0]oct-1-ylborane is the key intermediate in this migratory cross-coupling reaction, which promotes the development of other diverse migratory cross-coupling of borate complexes.

Abstract ：
Efficient synthetic methods are urgently needed to produce graphene nanoribbons (GNRs) with diverse structures and functions. Precise control over the topological edges of GNRs is also crucial for achieving diverse molecular topologies and desirable electro-optical properties. This study demonstrates a highly efficient "shotgun" synthesis of thiophene-backbone arcuate GNRs, offering a significant advantage over tedious iterative synthesis. This method utilizes a one-pot, three component Suzuki-Miyaura coupling for the precursor, followed by a Scholl reaction for cyclization. The resulting arcuate GNRs have sulfur atoms embedded in the carbon backbone with a combined armchair, cove, and fjord edge structure. This multi-edge architecture is further modified by high-yield oxidation of the electron-rich sulfur atoms to electron-deficient sulfones, enabling precise regulation of the GNRs' electronic properties. These arcuate GNRs with diverse edge structures, heteroatom doping and precise lengths open exciting avenues for their application in optoelectronic devices.

Abstract ：
Well-defined metal-organic frameworks (MOFs) provide an attractive platform for catalysis. Understanding the intrinsic structure-activity relationship of MOFs helps guide the design of novel catalysts. In this work, a new three-dimensional (3D) MnII(salen)-based MOF (1) with strong adsorption capacity and high selectivity for CO2 was synthesized. Through sequential demetallization and remetallization, the flexible tailoring of the metal centers was realized to obtain a series of remetallized MOFs (r1 M ; M = Mn, Co, Cu, Ni, V). Among them, r1 Co was proved to be the most active catalyst for the cycloaddition of CO2 and epoxides. Mechanistic studies reveal that r1 Co displays a high CO2 affinity and Lewis acidity. In addition, kinetic studies suggest that r1 Co has a lower activation energy than the original MOF (1) and demetallized MOF (d1). Remarkably, r1 Co could be reused five times without affecting its catalytic activity.

Abstract ：
The integration of electrocatalysis with biocatalysis has recently been developed for the stereoselective synthesis of valuable compounds. This integration leverages the high efficiency and exquisite selectivity of enzymes along with the tunability of electrochemical reactions, providing a versatile approach for asymmetric synthesis with broad prospects. In this highlight, recent advances and future development directions in asymmetric synthesis that integrate electrocatalysis with biocatalysis are presented and discussed. We foresee that more valuable stereoselective transformations using this integrated strategy will be developed in the future.

Abstract ：
Conventional approaches to unsymmetric disiloxanes involve the condensation of silanol with hydroxy-, chloro-, or alkoxysilanes, which suffers from several limitations such as limited substrate scope, the requisite use of stoichiometric bases, expensive transition-metal catalysts, and typically unsatisfactory product selectivity. Herein, we report a dehydrative cobalt catalysis for unsymmetric disiloxane from two different silanols, which features a low loading of the earth-abundant cobalt catalyst, easy operation, good functional combinability, and gram-scale preparation. Notably, this approach also enables the facile preparation of unsymmetric polysiloxanes. A highly selective and scalable dehydrative approach for the synthesis of unsymmetric disiloxanes and polysiloxanes is reported using Earth-abundant cobalt catalyst under an air atmosphere.

Abstract ：
We present here a catalytic enantioconvergent amination of alcohols for efficient access to chiral C2- and C3-substituted benzomorpholines. The racemic amino alcohol substrates of different substitution patterns, which are readily available from a common precursor, can be converted to the enantioenriched heterocycles in a highly atom- and step-economical fashion. In particular, an unprecedented asymmetric amination of racemic primary alcohols via dynamic kinetic resolution is achieved under cooperative iridium/iron catalysis, resulting in highly enantioen-riched C2-substituted benzomorpholines that aredifficult to access otherwise.
