Summary: Here, we present an anionic stereogenic-at-cobalt(III) complex catalysis strategy for the enantioselective halocyclization of ortho-alkynylanilines using N-halosuccinimide (NXS) as the halogen source. This method offers a distinct atroposelective approach to obtain axially chiral ortho-halo-C2-indole skeletons with excellent yields and good to high enantioselectivities (up to 99% yield, 99:1 er).

Summary: A family of well-defined lambda- and delta-configured octahedral cationic chiral-at-cobalt catalysts were expanded through postcomplexation of bromine-functionalized Co(III) complexes. This is the first example of direct modification of the ligand sphere of chiral Co(III) catalysts through Suzuki-Miyaura cross-coupling reaction. The chiral metal center is observed to be epimerized during the cross-coupling process.

Summary: A cyclometalated ruthenium complex with exclusively metal-centered chirality has been developed for the catalytic conversion of diazoketones to chiral flavanones. The reaction exhibits high yields (up to 99%) and high enantioselectivity (up to 96%). The unwanted C-O formation pathway was successfully suppressed in favor of a catalytic enantioselective ring-closing C(sp(3))-H carbene insertion, as supported by density functional theory calculations. This method provides access to a variety of chiral flavanones, which are privileged scaffolds with diverse biological activities.

Summary: Asymmetric hydrogenation of double bonds is an effective method for preparing chiral molecules, with noble metals and bidentate ligands showing remarkable reactivity. The development of chiral tridentate ligands has become increasingly important, enabling both reactivities and stereoselectivities in asymmetric hydrogenation. While noble metal catalysts with chiral tridentate ligands have made significant achievements, there is still a high demand for designing chiral tridentate ligands for earth abundant metal catalysts.

Summary: This work was motivated by a recent report on the substitution process of the cyclopentadienyl ring in [CpIr(COD)Br](+) with P(OMe)(3) under mild conditions. The study demonstrates that the first step involves an exergonic exo-addition of P(OMe)(3) to the carbon in the Cp-ring, followed by the substitution of a non-chelating (eta(4)-C5H5P(OMe)(3)) ligand.

Summary: We have developed a protocol for asymmetric synthesis of artificial amino acids with a 3-spiropyrrolidine oxindole skeletal structure containing continuous tetrasubstituted carbon stereocenters. This synthesis is achieved through a 1,3-dipolar cycloaddition reaction of azomethine ylides generated in situ with a chiral dehydroalanine Ni(II) complex. The reaction of the Ni(II) complex with isatins and amino acids in ethanol solvent resulted in diastereomeric complexes with high selectivities. Quantum chemical calculation explained the formation of different regioisomers for sarcosine and proline. The acidic decomposition of Ni(II) complexes yielded the desired unnatural complex amino acids, and the chiral auxiliary ligand could be recovered and reused for subsequent reactions.

Summary: A new family of Cu(II) and Ni(II) salen complexes was synthesized and characterized. These complexes were evaluated for their catalytic activity in the C-alpha-alkylation reaction of Schiff bases. It was found that introducing a chlorine atom into the phenyl ring of the substrate increased both the chemical yield and asymmetric induction. The highest enantiomeric excess was achieved using a Cu(II) salen complex based on (S,S)-cyclohexanediamine and salicylaldehyde at -20 degrees C. Bulky substituents in the ligand led to a decrease in both the enantioselectivity and chemical yield, with complete loss of stereoselectivity achieved with certain substituents at positions 3 and 5 of the phenyl ring.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
