Summary: Great improvements have been made in palladium-catalyzed radical reactions in recent years, offering more effective strategies for constructing complex heterocyclic compounds and applications in drug discovery. Reactions mediated by Pd(0)/(II)/(IV) typically undergo two-electron transfer processes, while those involving Pd(I) and Pd(III) usually occur via single electron transfer processes. Numerous methodologies involving palladium radical have emerged in the past five years since the publication of the review.

Summary: Late-transition-metal-catalyzed polymerization is a powerful protocol for preparing common polymers with well-defined structure. By controlling the reaction conditions or developing dynamic catalytic systems, the active sites can be influenced by external stimuli, enabling the production of multiple polymers from a monomer mixture using a single catalyst. In this review, various tunable modes of late-transition-metal-complex-catalyzed polymerization were discussed, including reaction conditions, redox, light or electrochemical properties, Lewis acids, and alkali metal cations.

Summary: Rare earth (RE) catalysts exhibit high catalytic activity in ring-opening polymerization, allowing for high molecular weight and polymerization rate and expanding the polymerization scope to traditionally non-polymerizable monomers. They also enable stereoselective polymerization and tailored polymer structures through slight modifications of ligands. The unique advantages of RE catalysts in controlling polymerization and structure are illustrated, along with a novel Janus polymerization mechanism providing a facile methodology to synthesize polymers with sophisticated chemical structures and topologies in one step. New catalysts and mechanisms of ring-opening polymerizations show potential in creating new materials.

Summary: In the last two decades, there has been a significant increase in interest in reactions catalysed by gold complexes due to their versatility in tolerating different functional groups and activating various unsaturated groups. This review focuses on gold-catalysed cycloisomerisation reactions of ynamides, diynes, and 1,n-enynes, which offer new possibilities for synthesising complex polycyclic chemical structures in a single step. These reactions provide valuable methods for synthesising fused spiro carbocycles, BODIPY cores, bicyclo[3.2.1]oct-2-ene, dihydro benzo[b]thiepine, disubstituted furans, spiroindolines, and bridged [n.2.1] skeletons, among others.

Summary: Silver complexes with N-heterocyclic carbene (NHC) ligands in combination with modified methylaluminoxane (MMAO) were used as catalysts for the synthesis of high molecular weight polyethylene. SEM observation confirmed the formation of polyethylene with ultra-high molecular weight. NMR investigation showed the transfer of NHC ligands from the silver complexes to aluminum, resulting in the formation of NHC aluminum complexes. These complexes promoted ethylene polymerization in the presence of Ph3C[B(C6F5)(4)] and organoaluminums, suggesting that the aluminum complexes are the actual active species in silver-catalyzed ethylene polymerization.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing.
