Tuning multiple noncovalent interactions to form multicomponent photoactive electron donor−acceptor (EDA) complexes for driving chemical reactions presents significant challenges yet holds profound implications. Hantzsch ester (HE) is recognized as an exceptional EDA donor, while it typically forms binary EDA complexes requiring stoichiometric amounts. Ternary EDA complexes involving HE in catalytic EDA systems remain scarce. Herein, we developed a H‐bonding‐assisted catalytic ternary EDA complex strategy employing HE for the synthesis of diverse isoquinoline‐1,3(2H,4H)‐diones. This operationally simple, visible‐light‐mediated platform efficiently converted primary, secondary, and tertiary carboxylic acids‐derived NHP esters into structurally diverse alkylated isoquinoline‐1,3(2H,4H)‐diones.
调整多个非共价相互作用形成多组分光活性电子供体-受体(EDA)复合物驱动化学反应提出了重大挑战,但具有深远的意义。汉奇酯(HE)被认为是一种特殊的EDA供体,而它通常形成二元EDA复合物,需要化学计量量。催化EDA体系中涉及HE的三元EDA配合物仍然很少。在此,我们开发了一种氢键辅助催化三元EDA配合物策略,利用HE合成了多种异喹啉- 1,3(2H,4H) -二酮。这个操作简单,可见光介导的平台有效地将伯、仲、叔羧酸衍生的NHP酯转化为结构多样的烷基化异喹啉- 1,3(2H,4H) -二酮。

An anionic N ‐heterocyclic carbene ligand with a weakly coordinating borate entity in the backbone (WCA‐NHC) is employed in the preparation of zwitterionic zinc complexes. Among these, zinc hydride species [(WCA‐IDipp)ZnH] 2 and [(WCA‐IDipp)ZnH(THF) 2 ] (WCA = B(C 6 F 5 ) 3 , IDipp = 1,3‐bis(2,6‐diisopropylphenyl)imidazolin‐2‐ylidene) were obtained either as a dinuclear zinc complex with two bridging hydrides or as a monomeric complex with a single terminal hydride, respectively. In these zwitterionic complexes, the positive charge at zinc is compensated by the anionic carbene ligand WCA‐IDipp. The overall neutral complexes display excellent solubility in organic solvents and were demonstrated as efficient catalysts in hydrosilylation reactions of aldehydes and ketones.

A triflic acid-mediated iodocarbocyclization of allylic and homoallylic sulfonamides with iodoarenes has been developed for the synthesis of benzo-fused saturated N-heterocycles. The combination of iodoarenes and triflic acid provides an efficient electrophilic iodine species for the iodocarbocyclization under ambient reaction conditions. A variety of sulfonamides derived from benzylamines, phenethylamines, and anilines were successfully transformed into the corresponding iodine-functionalized benzo-fused N-heterocycles in good to high yields.

Alkenyl nitrile derivatives represent important structural motifs found in a variety of natural products, active pharmaceuticals, and functional materials. Over the past decade, significant progress has been made in the development of efficient and selective catalytic methods for synthesizing alkenyl nitriles from alkenes, alkynes, and other precursors under relatively mild conditions with new synthetic technologies. However, a comprehensive summary of the synthesis of alkenyl nitriles has yet to be established in recent literature. This perspective highlights the latest advancements in the synthesis of alkenyl nitriles through the cyanation of alkenes, alkynes, and other starting materials, leading to functionalized alkenyl nitrile derivatives. The remaining challenges and future perspectives at the conclusion of the review is also discussed. It is hoped that this overview will inspire the development of novel approaches to access diverse alkenyl nitriles and facilitate their applications in organic chemistry and drug research.

In the past 10 years, P ‐hydrido‐1,3,2‐diazaphospholenes (DAP‐Hs) have been demonstrated to be able to reduce carbonyls, imines, and enones. However, the 1,6‐conjugate reduction transformations catalyzed by DAP‐Hs have been rarely studied. Herein, we developed a DAP‐catalyzed 1,6‐conjugate reduction of p ‐QMs with DAP‐Br as the precatalyst. Furthermore, the dienone could also be well tolerated in this transformation.

In this work, we report a novel approach for synthesizing P‐chiral phosphines through Mn(I)‐catalyzed enantioselective hydrophosphination of vinyl sulfones. A distinctive feature of this system is its solvent‐dependent stereoinversion, which enables the formation of products with opposite configurations using the same catalyst enantiomer. This phenomenon has been demonstrated across a range of vinyl sulfones and diarylphosphines, providing access to both configurations of P‐stereogenic phosphines with a single catalytic system.

A core challenge in photocatalytic water splitting for hydrogen production, as a clean method of hydrogen fuel generation, lies in simultaneously achieving efficient hydrogen production and long‐term stability of catalysts. Herein, we report the successful synthesis of a novel bimetallic cluster‐based metal‐organic framework (MOF) exhibiting exceptional performance for visible‐light‐driven photocatalytic hydrogen production. This unique MOF catalyst demonstrates a remarkably high hydrogen evolution rate of 20,778.7 μmol g −1 h −1 under visible‐light irradiation, significantly surpassing many MOF photocatalysts. Crucially, the MOF exhibits outstanding stability, maintaining its high catalytic activity over multiple reaction cycles without significant degradation. The synergistic effects within the bimetallic clusters and sensitively light‐responsive linkers are regarded as the key contributors to both the enhanced efficiency and remarkable durability. This work presents a highly promising and stable MOF photocatalyst for efficient solar energy harnessing towards clean hydrogen fuel generation.

Eco‐Friendly and Additive‐Free Synthesis of CP Bonds: Synergistic Catalysis by a Polyoxovanadate‐Based Cu–Organic Framework Using Molecular Oxygen 生态友好和无添加剂的C - γ - P键合成:基于多钒酸盐的cu -有机骨架利用分子氧的协同催化

Development of environmentally benign methods for CP bond formation is of great significance due to the extensive applications of organophosphorus compounds in pharmaceuticals and agrochemicals. Herein, we report a polyoxovanadate‐based Cu–organic framework, [Cu 3 (pty) 2 ][V 8 O 23 ]·H 2 O ( Cu‐POV , pty = 4′‐(pyridin‐4‐yl)‐2,2′:6′,2″‐terpyridine), for catalyzing the cross‐dehydrogenative coupling of N‐aryl tetrahydroisoquinolines with diarylphosphine oxides to form CP bonds using molecular oxygen (O 2 ) as an oxidant in green ethanol medium. The outstanding efficiency of Cu‐POV stems from a synergistic mechanism involving its structural Cu II and V V centers: the two activate the N‐aryl tetrahydroisoquinolines through single‐electron transfer and subsequently react with O 2 to generate the key superoxide radical species. The catalyst can be recycled at least six times without compromising performance, and applied in gram‐scale reaction with a turnover number of 2025.
由于有机磷化合物在医药和农用化学品中的广泛应用,开发环境友好的C -磷键形成方法具有重要意义。在此,我们报道了一个基于多氧钒酸盐的Cu -有机框架,[Cu 3 (pty) 2][v8 O 23]·h2o (Cu‐POV, pty = 4′‐(吡啶‐4‐基)‐2,2′:6′,2″‐三吡啶),用于催化N‐芳基四氢异喹啉与二芳基膦氧化物的交叉脱氢偶联,在绿色乙醇介质中使用分子氧(o2)作为氧化剂形成C -羟基- P键。Cu - POV的卓越效率源于其结构Cu II和V V中心的协同机制:两者通过单电子转移激活N -芳基四氢异喹啉,随后与o2反应产生关键的超氧自由基。该催化剂可循环使用至少6次而不影响性能,应用于克级反应,周转率为2025。
