Summary: Functionalising organic molecular photoswitches with metal complexes can alter and enhance their switching states, providing a promising basis for innovative smart molecular materials and molecular electronic devices. In this study, we synthesized and characterized mono- and bimetallic half-sandwich ruthenium and iron complexes functionalised with alkynyl dihydropyrenes (DHP). The introduction of the metal alkynyl moiety allowed access to additional redox and protonation states. However, the presence of an additional metal alkynyl moiety inhibited observable photochromic switching.

Summary: In this study, a series of hexanuclear chloride and sulfate Ni(II) and Cu(II) complexes were successfully synthesized from appropriate metal salts and octadecaaza macrocyclic ligands. The obtained coordination compounds were characterized using various methods, including elemental analysis, spectroscopic methods, magnetic measurements, and X-ray crystallography. The X-ray crystal structures revealed different coordination modes of the metal cations in the obtained coordination compounds. The folding conformation of the macrocyclic ligand depended on the number of metal cations bound within the macrocycle. All Ni(II) and Cu(II) coordination compounds exhibited paramagnetic behavior. The magnetic measurements showed that the magnetic behavior of certain complexes was dominated by the magnetic anisotropy of the metal ion, while others revealed small antiferromagnetic interactions within the metal units. The EPR experiments indicated that the predominant contribution to the orbitals occupied by the unpaired electrons in the ground state originated from d(x2-y2) orbitals.

Summary: The formation of polysubstituted cyclopropane derivatives in the gold(I)-catalyzed reaction of olefins and propargylic esters is of significant interest due to its potential usefulness in generating diversity. We tested a series of chiral gold(I)-carbene complexes as catalysts and achieved high enantioselectivity in the test reaction. However, the cis:trans selectivity of the transformation was independent of the catalyst. Although the reactions proceeded smoothly, the observed enantioselectivity varied greatly and a structure-property relationship could not be established.

Summary: The vibrational response of the activated C-D bond in the chloroform complex [Pt(C6H5)2(btz-N,N ')middotCDCl3] is studied using linear and nonlinear two-dimensional infrared (2D-IR) spectroscopy. The results show a red shift, broadening, and enhanced absorption of the stretching absorption band of the C-D bond in the metal-coordinated CDCl3 compared to uncoordinated CDCl3. This enhanced vibrational absorption is attributed to the increased electric polarizability of the activated C-D bond.

Summary: The demand for azobenzenes has exponentially increased due to their wide range of applications in various industries. In this study, we developed a method to synthesize azobenzenes by dehydrogenative coupling of anilines using Co-II(TPP) catalyst and 4-nitrophenyl azide oxidant species. The reaction yielded differently substituted azobenzenes with up to 72% yield along with 4-nitrophenyl amine as a stoichiometric by-product. The process demonstrated good sustainability by allowing almost quantitative recovery of pure 4-nitrophenyl amine, which can be converted back into the desired azide for efficient circular processing. Experimental data supported a radical mechanism mediated by a putative nitrene radical cobalt intermediate.

Summary: This study achieved the covalent immobilization of a free-base porphyrin on SBA-15 silica and utilized it for the catalytic cycloaddition of CO2 to three-membered rings. The catalytic system based on TPPH2@SBA-15/TBAX exhibited excellent activities in reactions with epoxides, N-alkyl, and N-aryl aziridines, resulting in cyclic carbonates and N-alkyl/aryl oxazolidinones, respectively. Notably, this is the first example of the heterogeneously catalyzed synthesis of N-aryl oxazolidinones from corresponding N-aryl aziridines. The methodology showed good scalability and recyclability, indicating its potential for practical applications.

Summary: A detailed computational analysis of the synthesis of thiazolidine-2-thiones by CS2 insertion into three membered aziridine rings was reported. DFT studies demonstrated the feasibility of the atom-efficient process using either the metal-free binary TPPH2/TBACl system or bifunctional TPPH4Cl2 molecules as catalysts. Mechanistic investigations revealed the crucial role of the adduct between TPPH2 and TBACl salts in the synthesis of thiazolidine-2-thiones, similar to the cycloaddition of CO2. The synthesis of thiazolidine-2-thiones was found to be more favorable than the synthesis of oxazolidin-2-ones, providing a pathway for the development of efficient and eco-compatible synthesis.

Summary: In this study, we investigate the structural changes and interactions of boron nitrilotriacetate under compression. We focus on the intermolecular interactions involving carbonyl groups, which may lead to polymerization reactions. However, X-ray diffraction experiments show no evidence of polymerization up to 16 GPa due to competing interactions. We use theoretical tools to explore the variable nature of these interactions and their changes during compression.

Summary: In this study, three new zinc(II) complexes were synthesized to further investigate their molecular structures and crystal packing. X-ray structural analysis revealed that the intramolecular resonance-assisted hydrogen bond ring remained intact in the zinc(II) complexes, and the presence of halogen bonds resulted in one-dimensional supramolecular polymers in the crystal packing. In the catalytic experiments, it was found that the zinc(II) complex Zn4 exhibited high catalytic activity and could efficiently catalyze the cycloaddition reaction to produce cyclic carbonates under solvent-free conditions.

Summary: In this study, we investigated the adsorption properties and dielectric behavior of a well-known metal-organic framework (MOF) called HKUST-1. By protecting HKUST-1 with amines, we aimed to reduce its hygroscopic nature, which is a disadvantage for its application as a low-dielectric-constant material. We also examined the structure of HKUST-1 under a strong electric field and found it to be robust. The presence of water molecules adsorbed by the MOF remained invisible in X-ray diffraction, except for those directly bound to the metal ions. However, when water was replaced with a more visible guest molecule, the cavity that traps the guest became more visible. Additionally, we demonstrated that impedance spectroscopy is a valuable tool for identifying water sorption in porous materials, providing complementary information to adsorption isotherms.

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.
