Pnictogen complexes are ideal for mediating multi-electron chemical reactions in two-electron steps. We report an Sb(v) bis-μ-oxo corrole that photochemically oxidises the C-H bonds of organic substrates. In the case of toluene, the substrate is oxidised to benzaldehyde, a rare example of a four-electron photoreaction.

Structure-Function Relationship of p-Block Bismuth for Selective Photocatalytic CO Reduction.

Selective photocatalytic reduction of CO to value-added fuels, such as CH, is highly desirable due to its high mass-energy density. Nevertheless, achieving selective CH with higher production yield on p-block materials is hindered by non-ideal adsorption of *CHO key intermediate and an unclear structure-function relationship. Herein, we unlock the key reaction steps of CO and found a volcano-type structure-function relationship for photocatalytic CO-to-CH conversion by gradual reduction of the p-band center of the p-block Bi element leading to formation of Bi-oxygen vacancy heterosites.

Reduction of the diamagnetic Ti(III)/Ti(III) dimer [ClTi(μ-NIm)] () (NIm = [1,3-bis(Dipp)imidazolin-2-iminato], Dipp = CH-2,6-Pr) with 4 and 6 equiv of KC generates the intramolecularly arene-masked, dinuclear titanium compounds [(μ-N-η-Im)Ti] () and {[(EtO)K](μ-N-μ:η-Im)Ti} (), respectively, in modest yields. The compounds have been structurally characterized by X-ray crystallographic analysis, and inspection of the bond metrics within the η-coordinated aryl substituent of the bridging imidazolin-2-iminato ligand shows perturbation of the aromatic system most consistent with two-electron reduction of the ring. As such, and can be assigned respectively as possessing metal centers in formal Ti(III)/Ti(III) and Ti(II)/Ti(II) oxidation states.

Article Synopsis
- The study introduces a new method for measuring electrochemical standard potentials and calculating bond dissociation free energies (BDFEs) of proton-coupled electron transfer (PCET) reagents in nonaqueous solvents like acetonitrile and tetrahydrofuran.
- This method, based on open-circuit potential (OCP) measurements, provides more accurate thermochemical values by directly assessing the overall thermodynamics of PCET reactions without relying on solvent p scales, making it suitable for any compatible solvent.
- OCP measurements enable precise evaluation of redox couples with complex electrochemical behaviors and have potential applications in both academic research and practical device development, although they currently cannot measure C-H bond processes

Storing and transferring electrons for multi-electron reduction processes are considered to be the key steps in various important chemical and biological transformations. In this work, we accomplished multi-electron reduction of a carboxylic acid a hydrosilylation pathway where a redox-active phenalenyl backbone in Co(PLY-O,O)(THF), stores electrons and plays a preponderant role in the entire process. This reduction proceeds by single electron transfer (SET) from the mono-reduced ligand backbone leading to the cleavage of the Si-H bond.
