Ru complexes containing N‐methyl‐1,3,5‐triaza‐7‐phosphaadamantane (mPTA) as catalysts for the isomerization of 2‐cyclohexen‐1‐ol

Applied Organometallic Chemistry, Volume 37, Issue 2, February 2023., 2023
The paper discusses the catalytic activity of [RuCp(H2O‐κO)(mPTA)2](CF3SO3)3 for the isomerization of the cyclic allylic alcohol 2‐cyclohexen‐1‐ol with good conversion and negligible metal losses. The complex [RuCp(H2O‐κO)(mPTA)2](CF3SO3)3·MeOH (4·MeOH) was synthesized and characterized by spectroscopic techniques and its crystal structure determined ...

Understanding the Role of Open Metal Sites in MOFs for the Efficient Separation of Benzene/Cyclohexane Mixtures [PDF]

arXiv
Separating C6 cyclic hydrocarbons, specifically benzene and cyclohexane, presents a significant industrial challenge due to their similar physicochemical properties. We conducted Monte Carlo simulations in the Grand-Canonical ensemble to acquire adsorption properties and separation performance data for benzene and cyclohexane in three metal-organic ...

Roadmap to Nanomedical Applications: Nanotoxicology and In Vitro Guidelines for Lanthanide‐Doped Luminescence Nanothermometers

Advanced NanoBiomed Research, EarlyView.
Lanthanide‐based luminescence nanothermometry holds multifaceted potential for nanomedical applications, yet despite significant research advances, clinical translation of the engineered nanomaterials is still controversial and widely disputed. This is related to crucial nanotoxicological aspects that must be addressed at the preclinical level ...

Synthesis and characterization of tetrafluorophenyl phosphonic acid functionalized polyacrylates as potential proton conducting materials in fuel cells

Journal of Applied Polymer Science, Volume 140, Issue 3, January 15, 2023., 2023
Fluorinated phosphonic acids are high‐performance materials for proton conduction applications. The bonding of phosphonic acids to a polymer backbone for application as electrolytes in polymer electrolyte membrane fuel cells is of broad interest. Here, we present acrylate‐based tetrafluorophenylene phosphonic acid polymers with high proton conductivity

Enantioselective Photochemical Generation of a Short‐Lived, Twisted Cycloheptenone Isomer: Catalytic Formation, Detection, and Consecutive Chemistry

Angewandte Chemie, EarlyView.
In a proof‐of‐concept study, it was for the first time shown that planar chiral trans‐cycloalk‐2‐enones, such as 2, can be formed enantioselectively from their cis‐isomers by triplet energy transfer from a chiral catalyst. Computational studies performed with cyclohept‐2‐enone and enone 1 provided invaluable insights into the mode of action of the ...

Nachhaltige Ansätze für die Synthese von Calciumsulfat‐Hemihydrat

Angewandte Chemie, EarlyView.
Calciumsulfat‐Hemihydrat (Bassanit) spielt im Bauwesen als hydraulisches Bindemittel eine wichtige Rolle. Aufgrund seiner Instabilität in Wasser beruht die industrielle Produktion hauptsächlich auf der thermischen Dehydratisierung von Gips. Dieser Review untersucht alternative und potenziell nachhaltigere Methoden zur Synthese von Bassanit, darunter ...

3‐[3‐(Phenalkylamino)cyclohexyl]phenols: Synthesis, biological activity, and in silico investigation of a naltrexone‐derived novel class of MOR‐antagonists

Archiv der Pharmazie, Volume 356, Issue 1, January 2023., 2023
Based on a simplified version of the morphinan scaffold, 3‐[3‐(phenalkylamino)cyclohexyl]phenol analogues were designed, synthesized and evaluated for their µ‐opioid receptor (MOR) antagonist activity in vitro and in silico. Docking studies indicate a peculiar combination of C‐1 stereochemistry and N‐substitutions as feasibly essential for MOR‐ligand ...

Elucidating the Boundary of Intercalation vs Sequestration in Supramolecular Polymers by Retrosynthetic Design Toward the Construction of Complex Supramolecular Systems

Angewandte Chemie, EarlyView.
By retrosynthetically analyzing the molecular structure of an intercalator, clear design principles toward supramolecular sequestration can be obtained. Investigating a model supramolecular polymer in the presence of these additives offers a general approach toward dilution‐induced polymerization and complex hybrid systems of dual sequestration and ...
