A Recyclable Nanoparticle-Supported Rhodium Catalyst for Hydrogenation Reactions

open access: yesMolecules, 2010
Catalytic hydrogenation under mild conditions of olefins, unsaturated aldeydes and ketones, nitriles and nitroarenes was investigated, using a supported rhodium complex obtained by copolymerization of Rh(cod)(aaema) [cod: 1,5-cyclooctadiene, aaema ...

Cross-Linked Polymeric Gels and Nanocomposites: New Materials and Phenomena Enabling Technological Applications

open access: yesMacromol, 2022
Cross-linked gels are synthesized by homo- and copolymerization of functionalized acrylamides. The gels swell in aqueous solution, and some of them (e.g., poly(N-isopropylacrylamide (PNIPAM)) also in organic solvents of low polarity (e.g ...

Die Umlagerung der Addukte von Säuren an Push-Pull-Acetylene : Ihre Anwendung in der Peptid-Synthese

open access: yesCHIMIA, 1979
Push-pull-acetylenes (1) react rapidly and smoothly with proton acids to yield 3-dialkylamino-3-X-acrylic derivatives, which rearrange under very mild conditions (and in the case of the adducts of carboxylic acids quantitatively) to 3-X-N,N-dialkyl ...

Pd-Catalyzed Enantioselective Hydroamidocarbonylation of α‑Substituted Acrylamides to Chiral Succinimides

open access: yes, 2022
With the aid of an innate amide group, an intramolecular Pd-catalyzed enantioselective hydroamidocarbonylation reaction of α-substituted acrylamides was developed, and a series of chiral 2-substituted succinimides were obtained in moderate to high yields

The effect of acrylamide on mitochondrial membrane potential and glutathione extraction in human spermatozoa: A laboratory study

open access: yesInternational Journal of Reproductive BioMedicine, 2020
Background: Acrylamide (AA) is a compound used in the industrial production of polyacrylamide. AAs affects by creating oxidative stress. It produces reactive oxygen species and leads to lipid peroxide.

In Search of Novel Degradation-Resistant Monomers for Adhesive Dentistry: A Systematic Review and Meta-Analysis

open access: yesBiomedicines, 2022
This study aimed to assess whether degradation-resistant monomers included in experimental dental adhesives can improve long-term bond strength compared to conventional monomers. This study followed the latest PRISMA guidance (2020).

Bile Acid Sequestrants Based on Natural and Synthetic Gels

open access: yesGels, 2023
Bile acid sequestrants (BASs) are non-systemic therapeutic agents used for the management of hypercholesterolemia. They are generally safe and not associated with serious systemic adverse effects.

Route to Air and Moisture Stable β‑Difluoroboryl Acrylamides

open access: yes, 2019
A method for the preparation of air stable difluoroboryl acrylamides is reported. In contrast to the ubiquitous organotrifluoroborate salts, difluoroboryl acrylamides are relatively nonpolar and are readily purified by silica chromatography ...
