Summary: The selective epoxidation of limonene using dioxomolybdenum((VI)) complexes anchored on TiO(2) nanotubes was studied, showing the influence of ligands on stereoselectivity. Complexes with non-chiral ligands exhibited moderate diastereoselectivity towards the cis-isomer of limonene. Contrary to this, the complex with Schiff base as chiral ligand showed an increase in diastereoisomeric excess, indicating an asymmetric double induction.

Summary: A highly selective epoxidation of α-pinene and R-carvone was achieved using a dioxo-Mo complex incorporated into a Metal-Organic Framework (MOF) type UiO-67. The reaction was facilitated by an oxygen atom transfer (OAT) using molecular oxygen as the oxidant. The catalytic system was characterized and the presence of dioxomolybdenum((VI)) units in UiO-67 was found to be proportional to the amount of epoxide monoterpene produced. Furthermore, the reaction selectivity was attributed to the absence of oxygen radicals in the reaction medium. The stability of the Mo complex was also demonstrated after multiple cycles of use.

Summary: The reaction between [IrCl(COD)](2) and dppe in a 1 : 2 ratio was studied under different conditions. The formation of [IrCl(COD)(dppe)], 1, was observed at room temperature without base. In the presence of a strong base, hydride complexes and deprotonation reactions were observed, leading to the formation of various complexes such as [IrH(1,2,5,6-eta(2):eta(2)-COD)(dppe)], [IrH(1-kappa-4,5,6-eta(3)-C8H12)(dppe)], and [IrH(1-kappa-4,5,6-eta(3)-C8H10)(dppe)]. The selectivity and mechanism of these reactions were explained using DFT calculations.

Summary: Simple synthetic routes for the regioselective deuteration of tris[2-(dimethylamino)ethyl]amine (Me6TREN) variants are described. Formation of imine with formaldehyde-d(2) from tris(2-aminoethyl)amine (TREN) and subsequent reduction with NaBD4 resulted in N[CH2CH2N(CD3)(2)](3) or d(18)-Me6TREN in 79% yield. A trisubstitution protocol from 2-bromo-N,N-dimethylacetamide and ammonium carbonate, followed by reduction of the N(CH2CONMe2)(3) intermediate with lithium aluminum deuteride, afforded N[CH2CD2N(CH3)(2)](3) or (d(6)-arm)-Me6TREN in three steps and 52% overall yield. A similar protocol using 2-bromo-N,N-dimethyl-d(2)-acetamide, obtained from d(4)-acetic acid in two steps, and reduction of the N(CD2CONMe2)(3) intermediate with lithium aluminum hydride, resulted in N[CD2CH2N(CH3)(2)](3) or (d(6)-cap)-Me6TREN in four steps and 13% overall yield.

Summary: This work investigated the thermal switchability of ethylene coordination/insertion to controlled radical polymerization of methyl acrylate using Brookhart-type α-diimine Pd-II catalysts. The impact of bulky α-diimine N-substituents was explored, revealing the reversible activation of the Pd-II-C bond and trapping during radical MA polymerization. DFT calculations evaluated the sterics effect on the stability of PE-MA-Pd-II chain-end structures and the bond dissociation-free energy for Pd(II)-C bond cleavage. Experimental investigations showed the failure of the Pd-II system to control radical polymerization of MA through OMRP mechanism.

Summary: The solution behavior of complex [Rh(COD)(& mu;-OAc)](2) in dichloromethane has been investigated in the absence and presence of PPN+OAc- using multinuclear NMR spectroscopy. The addition of PPN+OAc- results in the generation of [Rh(COD)(OAc)(2)](-) through equilibration. Rapid exchange between different Rh complexes and acetate ligands is observed at room temperature, but freezing the exchange at lower temperatures allows for the coalescence of certain NMR resonances.

Summary: This article reports the crystal structure and solid-state characterization of the 1:1 salt piperidinium sulfamethazinate. The salt exhibits hydrogen-bond donors and acceptors, which allows for the formation of supramolecular structures. The crystal structure of the salt reveals proton transfer between sulfamethazine and piperidinium ions, connected by N-H+...O and N-H (+)...N interactions. The self-assembly of sulfamethazine anions forms amine-sulfa C(8) motifs, and the supramolecular architecture displays interconnected sheets.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
