Design and synthesis of multifunctional ligands to study and prevent aggregation processes in Amyotrophic Lateral Sclerosis proteins
(2021-02-22)Amyotrophic lateral sclerosis (ALS) is an incurable lethal disease that affects motor neurons and its heterogeneity is reflected in various mutations among the sporadic ALS (sALS) and familial ALS (fALS) disease types. ... -
Synthesis and reactivity of succinylthioimidazolium salts: A unified strategy for the preparation of thioethers
(2020-12-21)Sulfur is one of the main group elements on our planet with a natural abundance of (0.46±0.15)w%. In its most common allotropic form sulfur is a yellow powder and exhibits a cyclic S8 structure. Apart of the cyclic S8 ... -
Transition Metal-Free Catalytic Systems for the Utilization of CO2 to Achieve Valuable Chemicals
(2020-11-03)The utilization of one of the most threatening greenhouse gases regarding the climate change could help changing its reputation from a harmful waste toward a green alternative feedstock. For the afore-mentioned reason, it ... -
Studies Toward Selenium-pi-Acid Catalyzed Oxidative Functionalizations of Olefinic and Acetylenic Multiple Bonds
(2020-09-24)The focus of this thesis was the oxidative functionalization of alkenes via selenium-pi-acid catalysis. In the realm of dual photoredox/selenium-pi-acid catalysis, the known methodology was expanded to the use of alcohols ... -
Metallaelectro-Catalyzed C─H Activations by 3d Transition Metals
(2020-09-17)The functionalization of C–H bonds largely relies on organic (pseudo-)halide electrophiles as coupling partners, which results in stoichiometric quantities of undesired by-products. Therefore, to achieve better resource ... -
Entwicklung regio- und enantioselektiver Transformationen an Alkenen mittels λ3-Iodan-Reagenzien bzw. chiraler Selen-π-Säure-Katalysatoren
(2020-09-02)In this thesis three novel oxidative functionalisations of alkenes are presented. The focus lay on the one hand on the development of the first aerobic phosphatation of alkens using a dual selenium-pi-acid-photoredox ... -
Sustainable Synthesis by 3d Transition Metal Electro-Catalyzed C─H Activation
(2020-01-20)During the last years, new opportunities are represented by the development of 3d transition metal-catalyzed C–H activation, with possible benefits due to the significantly lower toxicity, high natural abundance and ... -
Development of Photo-Induced C–H Activation by Copper and Ruthenium Catalysis
(2019-11-08)Within recent decades, transition metal-catalyzed C–H activation has become a valuable and versatile tool for organic synthesis. As C–H bonds are ubiquitous in organic molecules, the direct site-selective functionalization ... -
Host-Guest Chemistry of Acridone-based Coordiantion Cages
(2018-06-07)Supramolecular coordination cages, assembled from organic ligands and metal cations, are of broad interest due to their versatile topologies and properties. Discrete cages often possess a secluded cavity, which allows ...
