Summary: The zirconium catalyzed hydroaminoalkylation of alkenes with N-aryl- and sterically demanding N-alkyl-alpha-arylated secondary amines using commercially available Zr(NMe2)(4) is reported. The catalyst is compatible with challenging alpha-heteroarylated amines and functionalized alkene substrates, providing a new disconnection strategy for selectively substituted saturated alpha-arylated heterocycles.

Summary: By utilizing a specific titanium precatalyst, the hydroamination of alkynylphosphines to prepare 2-amino-phosphines in high yield and on gram scale has been achieved. The broad substrate scope allows for the rapid assembly of a variety of ligands in one pot, making preparation of metal P,N-complexes for catalysis or small molecule activation easy and efficient.

Summary: This study presents a method for the direct alkylation of unprotected amine heterocycles using an early transition-metal system, allowing for short reaction times and selective formation of branched reaction products in most cases. By avoiding the use of high loadings of precious metal catalysts, this method offers a more efficient approach to alkylate saturated N-heterocycles.

Summary: The reaction of (tBuO(2)CN)(2) with 9-BBN leads to the formation of a bicyclic heterocyclic compound, while its reactions with BF3 or [Et3Si][B(C6F5)(4)] result in the isolation of different compounds. Computational studies reveal that the steric and electronic properties of the Lewis acid are important in the formation of one of the compounds.

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: In this study, a series of structurally rigid cyclooctyl-fused iminopyridine iron complexes were synthesized and used with methylaluminoxane for isoprene polymerization. The extent of steric hindrance of the ligand framework was found to significantly affect catalytic performance, with less hindrance leading to better activity and stability.

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: This study successfully fabricated visible-light-responsive three-dimensional core-shell CoSe2/ZnIn2S4 heterostructures and achieved attractive activity in photocatalytic hydrogen evolution. The presence of CoSe2 improved light absorption and accelerated charge transfer kinetics. The strong interaction between CoSe2 and ZnIn2S4 reduced charge recombination, further enhancing photocatalytic activity for hydrogen evolution.

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. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.

Summary: Developing low-cost and self-supported bifunctional catalysts is crucial for highly efficient water splitting devices. In this study, nano-NiFe2O4 was directly grown onto iron foil surface and Sn4+ was introduced into the NiFe2O4. The resulting Sn-NiFe2O4/IF showed low overpotentials and high current densities during oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), making it a promising catalyst for large-scale hydrogen production.
