Aktivierung von Metallkomplexen durch Ultraschallwellen für eine gezielte Krebstherapie

Angewandte Chemie, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

Angewandte Chemie, EarlyView.
We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐

Structural Analysis of Fast-Growing Aspen Alkaline Peroxide Mechanical Pulp Lignin: A Post-Enzymatic Treatment

BioResources, 2016
An enzymatic mild acidic hydrolysis was used to separate and purify residual lignin from alkaline peroxide mechanical pulp (APMP). Using the optimum conditions for the laccase treatment (pH 4.5, temperature 50 °C, lignin consistency of 1%, a reaction ...

Borankatalysierte Dehydrierung von Wasser an Dioxaphospholen und ‐phospholanen

Angewandte Chemie, EarlyView.
Die borankatalysierte Dehydrierung von Phenylphosphinatestern, die aus der Reaktion von Dioxaphospholen und ‐phospholanen mit Wasser oder Luftfeuchtigkeit unter milden Bedingungen gebildet werden, wird beschrieben. Der Mechanismus dieser Umwandlung wurde durch kinetische Messungen und DFT‐Rechnungen untersucht, die auf die Wasserstofffreisetzung aus ...

Quantitative analysis of phospholipids by 31P-NMR.

Journal of Lipid Research, 1988
High-field 31P nuclear magnetic resonance spectroscopy was used to quantitate phospholipids in mixtures in organic solvents. The sample is dissolved in chloroform-methanol and analyzed at 161.7 MHz with decoupling of the protons.

A 2-(2’-pyridyl)quinoline ruthenium(II) complex as an active catalyst for the transfer hydrogenation of ketones

Open Chemistry, 2016
The ruthenium(II) complex cis-[RuCl2(PPh3)2(L1)] (1) where L1 = 2-(2’-pyridyl)quinoline was obtained in high yield from the reaction of [RuCl2(PPh3)3] with L1. The new compound was characterized by different spectroscopic methods including FT-IR, UV-Vis,
