Summary: This study examines the simulated structures of K-, Mg-, and Ca-magadiites based on Namagadiite. The results show that Na- and K-magadiites have longer coordinated bond lengths and higher basal spacing values, while solids containing divalent cations form the strongest hydrogen bonds between water molecules and layers. Vibrational analysis identifies different stretching and bending motions of water molecules, and simulated-experimental comparison suggests a sequential adsorption of water molecules in dehydrated samples. Thermodynamic analysis confirms the difficulty of achieving complete sodium-potassium exchange, except for Ca-magadiite which can form spontaneously.

Summary: Three stable N,N'-diarylated dihydroazaacene radical cations were prepared by oxidizing neutral N,N'-diarylated dihydroazaacenes synthesized through palladium-catalyzed Buchwald-Hartwig aminations of aryl iodides. Both neutral and oxidized species were investigated using UV-vis spectroscopy, single crystal analysis, and DFT calculations, showing surprising stability with their absorption spectra remaining unchanged in dichloromethane for at least 24 hours at ambient conditions.

Summary: In this study, cyclic(alkyl)(amino)carbenes (CAACs) were found to be one-electron reductants, forming transient radical cations as detected by EPR spectroscopy. The reactivity of the disclosed CAACs was utilized to synthesize a new class of Thiele and Chichibabin hydrocarbons based on acyclic(amino)(aryl)carbene. Additionally, the acyclic(amino)(aryl)carbene-based Chichibabin's hydrocarbon showed a significant population of the triplet state at room temperature.

Summary: A series of extremely electron-rich N-heterocyclic olefins (mNHOs) with an exocyclic CC-double bond were synthesized and characterized. The reactions of mNHOs with arylidene malonates were studied and the nucleophile-specific parameters N and sN of mNHOs were obtained. The nucleophilicity of mNHOs was found to be much higher than conventional NHOs and the reactivity parameters allowed prediction of reaction scope with other electrophilic partners.

Summary: This work presents a method to monitor anthracene radical-mediated oxidation reactions using EPR spectroscopy, with detailed investigation of the reaction mechanism in concentrated sulfuric acid. The study identified the formation of the anthracene dimer product and characterized the EPR-spin transitions of the radical intermediate. Kinetic analysis revealed that radical intermediate formation is an autocatalytic process, dimerization is a pseudo-zero order reaction, and the rate-determining step has a half-life of 48 +/- 2 minutes at 25.0 degrees C.

Summary: Coumarin derivatives are stable molecules with complex biodegradation routes in waste-waters. The study investigated the reactivity of these derivatives with hydroperoxyl radical, proposing two possible reaction mechanisms. The preferred mechanism was determined to be RAF-HAA, with the highest reaction rate observed at position C3 of the molecule. UV-Vis spectrophotometry and excited state optimization further supported the preferred mechanism.

Summary: A series of nickel(II) porphyrins with bulky nitrogen donors were synthesized via Ullmann methodology or Buchwald-Hartwig amination reactions. X-ray structures of some compounds were determined and the electrochemical behavior was analyzed. Spectroelectrochemical measurements were used to study the electron exchange process, and electron paramagnetic resonance (EPR) and electron nuclear double resonance spectroscopy (ENDOR) were employed to determine the delocalization of radical cations and the coupling constants, respectively. DFT calculations were performed to support the EPR data.

Summary: A novel neutral diradical and its corresponding dimers were investigated. The diradical was found to be in a triplet ground state with doubly degenerate singly occupied molecular orbitals. Upon preparation, the diradical underwent sigma-dimer formation, resulting in two types of dimers. One dimer existed only in the crystalline state, while the other dimer was observed only in solution. Temperature-dependent spectroscopic measurements revealed that these dimers were in equilibrium in solution, with the reversible formation/cleavage of sigma-bonds mediated by the neutral diradical.

Summary: Diiron mu-aminocarbyne complexes can be synthesized by reacting sodium cyanate and tetrabutylammonium thiocyanate with pre-prepared diiron aminocarbyne complexes, yielding different substituted diiron cyanide complexes with yields of 67-81%, through substitution of the acetonitrile ligand. When reacted with potassium selenocyanate at reflux temperature, cyanide complexes can be obtained with yields of 45-67%. When reacted at room temperature in acetone, a small amount of potassium selenocyanate complexes can be obtained. All products were fully characterized and the chiral structure was determined by single crystal X-ray diffraction. DFT calculations shed light on the coordination mode and stability of the {NCSe-} fragment.

Summary: Diiron vinyliminium complexes are promising organometallics with potential anticancer activity. The synthesis and evaluation of [Fe2Cp2(CO)(mu-CO){mu-eta(1):eta(3)-C(R-3)C(R-4)CN(R-1)(R-2)}]CF3SO3 (2a-c, 4a-d) complexes were performed, including their solubility in D2O, Log P-ow, stability in D2O/Me2SO-d(6) mixture, and antiproliferative activity against ovarian cancer cell lines A2780 and A2780cisR, as well as the nontumoral cell line Balb/3T3 clone A31. The cytotoxicity data of 50 vinyliminium complexes were correlated with the structural properties, showing a positive correlation between octanol-water partition coefficient and relative antiproliferative activity on ovarian cancer cell lines. However, the effects of different substituents provided guidelines for the development of novel, more effective compounds. Three additional complexes (4p-r) were designed, synthesized, and biologically investigated, revealing their ability to inhibit thioredoxin reductase enzyme and induce cancer cell production of reactive oxygen species.
