Summary: The reactivity of (L-Tr)Co towards various aryl azides was investigated to understand the electronic structure and reactivity of dipyrrinato cobalt aryl nitrenoid complexes. The synthesis of a Co-II diketimide complex and its reversible C-C bond cleavage to yield a monomeric Co nitrenoid complex was demonstrated. The study revealed the pre-equilibrium between [(L-Tr)Co(NC6F5)](2) and (L-Tr)Co(NC6F5), as well as the reductive coupling, fluoride expulsion, and N-group transfer reactivity of (L-Tr)Co(NC6F5).

Summary: We have reported a nickel complex that can catalyze the oxidation of ammonia to dinitrogen under ambient conditions. By using aryloxyl or N-oxyl radicals as H atom acceptors, the N-H bonds of coordinated NH3 ligands can be cleaved to generate N-2 molecules. Isotopic nitrogen studies have identified a bridging Ni-hydrazine product, supported by computational models, indicating a bimetallic homocoupling mechanism for N-N bond formation.

Summary: This study reports the isolation and characterization of a new terminal Co-III-oxo complex capable of hydroxylation of aliphatic C-H bonds. The experimental and DFT analysis reveal that the reaction is endergonic at the initial C-H activation step but driven by an extremely exergonic radical rebound step, similar to cytochrome P450 enzymes. The rapid C-H hydroxylation reactivity displayed in this well-defined system provides insight into biological systems and synthetic oxidants.

Summary: Polystyrene upcycling is crucial for reducing plastic waste, and photooxidative degradation is an effective method for converting polystyrene into valuable compounds. Investigating the mechanism of this degradation process is important in understanding the formation of different small molecules. By studying the reactivity differences between chlorine and bromine radicals, it was found that chlorine radical mainly produces benzoic acid, while bromine radical shows a preference for acetophenone. Further mechanistic studies revealed that activation of C-H bonds and hydrogen atom transfer are essential for acetophenone formation. Exogenous bromine sources were added to increase HBr concentration and improve acetophenone yield, becoming the major degradation product. These insights into polystyrene degradation mechanism will enable enhanced product selectivity.

Summary: This study calculated the rate constants of the reaction between cyclopentanol and hydroxyl radical using multistructural canonical variational transition state theory. The results highlighted the importance of variational and multistructural torsional anharmonicity effects, with quantum tunneling effect being negligible. While the total rate constants were in good agreement with literature estimates, significant discrepancies were observed in the branching ratios of reaction channels.

Summary: Copper nitrite reductases convert nitrite ions to nitric oxide and nitrous oxide at high levels of nitrogen oxide flux. The assembly of nitric oxide at a single copper site to form copper cis-hyponitrites has been demonstrated in the presence of an external reductant. Furthermore, the removal of a fraction of the structure in the copper cis-hyponitrite complex can be achieved by adding specific reagents, resulting in the formation of a spectroscopically similar anion. These studies provide insights into the reductive coupling of nitrogen oxides at a single copper center and the utilization of the strong oxidizing power of nitrite.

Summary: The nitrite-to-NO transformation is important, but the reaction at the [Zn-II] site is slow and not well understood. It has been discovered that [(Bn ( 3 ) Tren)Zn-II-ONO](ClO4) can react mildly with nitrite due to its mild electrophilic nature. The presence of sulfane sulfur and persulfides from the reaction of thiol and [Zn-II]-nitrite assists in the conversion to NO.

Summary: (Per)thionitrite (SNO-/SSNO-) intermediates play important roles in modulating nitric oxide (NO) and hydrogen sulfide (H2S) dependent bio-signalling processes. This study reveals that stable thiocarbonyl compounds can react with nitrite anion to yield SNO-/SSNO-. The presence of both NO2- and thiocarbonyl motifs in the biological context suggests their synergistic activation leading to the generation of NO gas and various reactive sulfur species via SNO-/SSNO-.

Summary: Photosynthesis is a vital process for storing solar energy as chemical energy, and the efficiency of this process is crucial. In this study, the turnover efficiency of different S states in the Photosystem II reaction was quantified using electron paramagnetic resonance spectroscopy. The results showed that the turnover efficiencies were limited by reactions occurring in the water oxidizing complex. Structural changes and chemical events during the reaction cycle were found to be correlated to the low efficiencies. These findings were confirmed by measurements of flash-induced oxygen release patterns and explained based on S state dependent structural changes at the CaMn4O5-cluster.

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.
