Summary: Rate constants for the reactions of muonium (Mu) with H2O2 and D2O2 have been determined at different temperatures and pH values. The results show that Mu reacts with H2O2, HO2-, and O- to form MuH and MuOH. The isotope effect is observed for the undissociated peroxide, while for the anions the effect is negligible or slightly in the opposite direction. These findings have potential significance for the management of radiolysis products in the nuclear industry.

Summary: The diastereoselective alpha-hydroxylation of N-tertbutanesulfinyl metallodienenamine and metalloenamines with Davis oxaziridine has been achieved with high yields and diastereomeric ratios. The choice of metal bases dramatically influences the diastereoselectivity and stereoselectivity of the reaction. DFT computational modeling has provided mechanistic insights, suggesting the importance of aza-enolate geometry in the facial approach. A one-pot protocol for the asymmetric synthesis of 1,2-amino alcohols has been developed.

Summary: An isolable iron(IV) imido complex with trifluoromethyl on nitrogen, [(IPr)Fe(NC(CF3)(2)Ph)(2)], was reported, demonstrating long Fe-N(imido) bonds, bent Fe-N(imido)-C(imido) alignments, and the ability to undergo intramolecular C-H bond activation reaction to transform into an iron(II) amido complex. Theoretical study suggests a hydrogen-atom-abstraction mechanism in the C-H bond activation reaction with low activation barrier due to the electron-withdrawing nature of the trifluoromethyl group.

Summary: Glutathione depletion is a promising strategy for the development of non-platinum anticancer drugs. This study introduces a series of electrophilic (salen)osmium(VI) nitrides that react with glutathione to produce (salen)osmium(III) ammine compounds. In vitro experiments show that these osmium(VI) nitrides exhibit similar cytotoxicity to cisplatin against various types of carcinoma. Mechanistic studies suggest that one representative compound (1) induces glutathione depletion, reactive oxygen species generation, endoplasmic reticulum stress, and ultimately leads to death receptor-mediated apoptosis and autophagy in lung cancer cells. In vivo evaluations demonstrate that 1 effectively inhibits tumor xenograft growth without causing weight loss.

Summary: Although the oxidation of alcohols by metal nitrido complexes has not been studied extensively, this report demonstrates the visible-light-induced oxidation of primary and secondary alcohols to carbonyl compounds using a strongly luminescent osmium(VI) nitrido complex (OsN). The proposed mechanism involves the rate-limiting hydrogen-atom transfer from the alpha-carbon of the alcohol to OsN*. Attempts to catalytically oxidize alcohols by OsN* using PhIO as the terminal oxidant resulted in the formation of novel osmium(IV) iminato complexes where the nitrido ligand is bonded to a 6-carbon of the alcohol. Experimental and theoretical studies suggest that OsN* is reductively quenched by PhIO to generate highly active PhIO+ oxidant, which readily undergoes alpha- and 6- C-H activation of alcohols.

Summary: We present an efficient visible light-driven CO2 reduction system that operates in water without the use of noble metals or rare materials. By employing a cobalt complex as a catalyst, an organic triazatriangulenium salt as a photosensitizer, and BIH + TEOA as a sacrificial reductant, we achieved CO and formate production with high selectivity and total turnover numbers exceeding 3700. The addition of a weak Brönsted acid further improved the catalysis, resulting in a selectivity of 93% and a total turnover number of 19,000 for CO production. The photocatalytic system demonstrated excellent performance even in pure water, with a turnover number of 2600 and a selectivity of 94% using TEA as the sacrificial reductant.

The photoreaction of OsN with organic sulfide, such as diisopropyl sulfide, also results in S atom abstraction and the formation of OsNS and Os-NvC(CH3)(2). The X-ray crystallographic study reveals the N-O, N-S, and N-Se bond distances of 1.206, 1.507, and 1.675 Å in (PPh4)[Os-II(NuE)(L)(CN)(3)].

Summary: The three-body fragmentation of C2H23+ to H+ + C+ + CH+ resulting from CH and CC bond breaking is studied under 50-keV/u Ne8+ impact. All three fragments are detected in coincidence with a scattered projectile (either Ne7+ or Ne6+) using a reaction microscope, and their momentum vectors and kinetic energies are obtained. Four distinct structures are observed in the energy correlation spectra, indicating multiple fragmentation mechanisms contributing to the H+ + C+ + CH+ channel. Newton diagrams and Dalitz plots are used to trace these fragmentation mechanisms. It is found that both concerted fragmentation and sequential pathways involving CH bond breaking prior to CC contribute to this channel. The possible electronic states of the C2H23+ precursor that contribute to the identified fragmentation mechanisms are analyzed using quantum chemical calculations. Furthermore, the influence of collision dynamics between the projectile and target on the dissociation mechanisms is discussed by comparing the contributions from the T1I2 channel and the reversed T2I1 channel, where one electron is transferred while ionizing the other two. The T2I1 channel is observed to be more efficient in initiating fragmentation mechanisms with higher kinetic energy release.

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.
