Summary: The report explores a potential method based on a hydroboration/copper-catalyzed carboxylation reaction sequence to synthetically access fluorinated carboxylic acids. DFT calculations support the possibility of obtaining these compounds from simple fluorinated alkenes and gaseous carbon dioxide. This paves the way for the future preparation of this class of chemicals.

Summary: In this study, we design and synthesize a series of water-stable and temperature-stable mCB-EuyTb1-y MOFs and report the tunable emission, energy transfer, and time-dependent emission of these materials. The quantum yield is significantly increased and the lifetime luminescence is enhanced and tunable, achieved by a highly effective energy transfer process. The time-dependent emission and high quantum yield provide a simple method for designing high-security anticounterfeiting materials.

Summary: Four novel Ce-III mononuclear complexes with different coordination numbers have been synthesized and characterized. Magnetic measurements and analysis reveal their field-induced single-ion magnet behavior and different spin relaxation mechanisms. Multiconfigurational calculations provide additional information on the axiality of the compounds.

Summary: In this study, the anion binding capabilities of perfluorinated polymercuramacrocycles were investigated using structural and computational analysis. The coordination preference of these cyclic systems towards specific Lewis bases, both anionic and neutral, were explored using the Cambridge Structural Database (CSD). Interaction energies with different electron-rich species were computed and further analyzed by energy decomposition analysis. Additionally, the natural resonance theory and natural bond orbital analyses were used to understand the key orbitals involved in the interaction and their impact on the final geometry of the adduct. Furthermore, a generalization of the findings using molecular orbital theory provided insights into the formation of the pseudo-octahedral second coordination sphere in linear Hg(II) complexes.

Summary: In this study, the coordination of E-C bonds (E = Zn, Mg, Al) to the Mo atoms of dimolybdenum complexes and the formation of dimolybdenum compounds through reactions with zincocenes were explored. The bonding mechanism of the reported H-Mo strictly equivalent to Mo-E-R rings was revealed through DFT calculations and NBO analysis.

Summary: This study developed a new colloidal synthetic method for the preparation of hybrid Au-Ag2X nanoparticles in a simple way. The formation of stable ternary AuAg3X2 phase through a solid-state electrochemical reaction at the solid-solid interface facilitated the selective hetero-attachment of Au and Ag2X nanoparticles in solution and stabilized the whole hybrid system.

Summary: The Cu-catalyzed Suzuki-Miyaura coupling between highly fluorinated aryl boronate esters and aryl iodides has been investigated using DFT calculations. The proposed reaction mechanism suggests that the rate-determining step is the oxidative addition of the aryl iodide to the copper catalyst. Computational studies on alternative reactions with different substituents provide a reaction barrier database that considers the electronic properties of various functional groups. Statistical learning techniques, specifically multi linear regression (MLR) modeling, reveal that both electron poor aryl boronate esters and aryl iodides result in lower reaction barriers. The combination of the reaction barrier database and MLR models allows for the generation of an electronic substrate map for estimating the reaction outcome in analogous Suzuki-Miyaura reactions between aryl boronate esters and iodobenzenes.
