Summary: The anodic oxidation of tetrafluoroborate anion produces the Lewis acid BF3, which yields a stable system when carried out in an imidazolium ionic liquid. Computational analysis suggests a higher stability for the BF3/BMIm-BF4 system compared to BF3·Et2O. Studies on the effects of substituents on the imidazolium ring and the electrochemical configuration on BF3 reactivity were conducted in a model reaction involving styrene oxide isomerization.

Summary: The Pd(II) complexes [Pd(Cp)(L)(n)](m)[BF4](m) were synthesized by reacting cationic acetylacetonate complexes with cyclopentadiene in the presence of BF3 center dot OEt2.

DFT calculations and QTAIM analysis supported the existence of these interactions. The cationic Pd catalyst precursors with monophosphines showed high catalytic activity for the telomerization of 1,3-butadiene with methanol, and complex [Pd(Cp)(TOMPP)(2)]BF4 exhibited efficient catalytic activity for the polymerization of phenylacetylene.

Summary: Researching carbon dioxide removal from flue gas and natural gas is crucial. Metal-organic frameworks (MOFs) are commonly used in adsorption due to their high surface area, porosity, and chemical properties. An ultra-microporous MOF CPM-20(Co) with mixed ligand was synthesized using inexpensive ligands. The material exhibited high selectivities and low regenerative energy, making it a promising option for CO2 separation in industries.
