Article Abstract

It works ether way: Labile adducts of dialkyl ethers with the electrophilic borane B(C6F5)3 are shown to scramble HD to H2 and D2 and catalyze the hydrogenation of 1,1-diphenylethylene.

Marine biofouling poses significant economic and environmental challenges, highlighting the need for effective antifouling coatings. We report amphiphilic poly(SBMA--EGDEA) copolymer coatings that resist both marine diatom adhesion and sediment adsorption. The coatings were synthesized via surface-initiated ATRP and RAFT polymerization using hydrophilic sulfobetaine methacrylate (SBMA) and hydrophobic ethylene glycol dicyclopentenyl ether acrylate (EGDEA).

Background: Anesthetic exposure in young children raises concerns about neurodevelopmental safety, with preclinical evidence suggesting potential neurotoxicity of volatile anesthetics. This study aimed to assess whether the combination of dexmedetomidine and remifentanil, by reducing sevoflurane exposure, has any differential effect on neurodevelopmental outcomes in young children compared with sevoflurane alone.

Methods: This study was a prospective, double-blind, randomized clinical trial including children younger than 2 yr undergoing nonstaged, nonrepetitive surgeries.

The gas-phase structures of dibenzo-24-crown-8 (DB24C8) and dinaphtho-24-crown-8 (DN24C8) complexes with divalent metal ions (Mg, Ca, Sr, Ba, Fe, Ni, and Zn) were investigated by cryogenic ion mobility-mass spectrometry (IM-MS) in combination with density functional theory calculations. Several complexes, particularly those of DN24C8, exhibited multiple coexisting conformers. DFT-optimized structures were classified based on the relative orientation of the two aromatic rings in the crown ether.

The design, synthesis, and characterization of a series of supramolecular receptors based on electron-deficient aromatic systems capable of engaging in anion-π interactions are reported. Receptors 1 and 3 combine an electron-poor aromatic scaffold with a cation-binding crown ether unit. Binding studies monitored by H NMR titrations in acetonitrile revealed that these receptors exhibit enhanced affinity for bromide anions in the presence of sodium cations, indicating cooperative ion-pair recognition.

Structure elucidation and antioxidant activity of the radical-induced oxidation products obtained from procyanidins B1 to B4.

A- and B-type procyanidins (PCs) are widely known for their health-promoting properties, such as antioxidant activity. The limited availability of reference substances represents a major challenge, resulting in a low number of systematic studies on their health benefits. In our study, the optimised 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-induced oxidation of the B-types B1 and B2 was carried out yielding the corresponding A-types A1 (1) and A2 (2), which have an additional ether bridge between C2--C7, whereas oxidation of B3 and B4 produced a six-membered spirocyclic ring system including a spiro-carbon atom at C8t (3-5).
