We report our investigation into the MCU-inhibitory activity of Co3+ complexes in comparison to Ru265. These compounds reversibly inhibit the MCU with nanomolar potency. Mutagenesis studies and molecular docking simulations suggest that the complexes operate through interactions with the DIME motif of the MCU pore.

Monoanionic, bidentate-auxiliary-directed, cobalt-catalyzed C-H bond functionalization has become a very useful tool in organic synthesis. A comprehensive investigation into isolated organometallic intermediates and their reactivity within the catalytic cycle is lacking. We report here mechanistic studies of cobalt-catalyzed, aminoquinoline-directed C(sp)-H bond functionalization.

Chiral allyl amines are important structural components in natural products, pharmaceuticals, and chiral catalysts. Herein, we report a cobalt-catalyzed enantioselective reductive coupling of imines with internal alkynes to synthesize chiral allyl amines. The reaction is catalyzed by a cobalt complex derived from commercially available bisphosphine ligand utilizing zinc as the electron donor.

Heterobimetallic complexes of an ambidentate deferiprone derivative, 3-hydroxy-2-methyl-1-(3-((pyridin-2-ylmethyl)amino)propyl)pyridin-4(1H)-one (PyPropHpH), incorporating an octahedral [Co(4N)] (4N = tris(2-aminoethyl)amine (tren) or tris(2-pyridylmethyl)amine (tpa)) and a half-sandwich type [(η--cym)Ru] (-cym = -cymene) entity have been synthesized and characterized by various analytical techniques. The reaction between PyPropHpH and [Co(4N)Cl]Cl resulted in the exclusive (O,O) coordination of the ligand to Co(III) yielding [Co(tren)PyPropHp](PF) () and [Co(tpa)PyPropHp](PF) (). This binding mode was further supported by the molecular structure of [Co(tpa)PyPropHp](ClO)(OH)·6HO () and [Co(tren)PyPropHpH]Cl(PF)·2HO·CHOH (), respectively, obtained via the slow evaporation of the appropriate reaction mixtures and analyzed using X-ray crystallography.

Parasitic structure defect blights sustainability of cobalt-free single crystalline cathodes.

Chemical Sciences and Engineering Division, Argonne National Laboratory, Lemont, IL, USA.

Recent efforts to reduce battery costs and enhance sustainability have focused on eliminating Cobalt (Co) from cathode materials. While Co-free designs have shown notable success in polycrystalline cathodes, their impact on single crystalline (SC) cathodes remains less understood due to the significantly extended lithium diffusion pathways and the higher-temperature synthesis involved. Here, we reveal that removing Co from SC cathodes is structurally and electrochemically unfavorable, exhibiting unusual voltage fade behavior.

A search for switchable molecules has afforded a family of cobalt complexes featuring derivatives of 2-aminophenol: 4,6-di--butyl aminophenol (HL) and 2-anilino-4,6-di--butyl aminophenol (HL). The heteroleptic cobalt complexes incorporate a Metpa ligand (tpa = tris(2-pyridylmethyl)amine; = 0-3), which involves the methylation of the 6-position of the pyridine ring). Eight members of this family have been synthesized and characterized: [Co(HL)(tpa)](BPh) (), [Co(HL)(Metpa)](BPh) (), [Co(L)(Metpa)](BPh) (), [Co(HL)(Metpa)](BPh) (), [Co(L)(Metpa)](BPh) (), [Co(HL)(tpa)] (BPh)(ClO) (), [Co(L)(tpa)](BPh)(ClO) () and [Co(HL)(Metpa)](BPh) (), where the aminophenol-derived ligands are monoanionic in either the open shell radical iminosemiquinonate (L) or the closed shell protonated aminophenolate (HL).
