Molecular Ruthenium based Water Oxidation Catalysts and their Immobilization on Electrode Surfaces
(2022-02-11)Ruthenium complexes are valuable in the field of catalytic water oxidation. Their stability and molecular nature allow for detailed mechanistic insight, and they can be synthetically modified to enhance their activity. ... -
Merging Electrosynthesis with 3d Transition Metal-Catalyzed C–H Transformations
(2021-07-12)In recent years, oxidative C–H transformations have emerged as increasingly powerful tools in molecular syntheses. However, despite great progress towards more atom and step economic synthetic methods, oxidative couplings ... -
S-Substituted Dibenzothiophenium Triflates: Synthesis, Structure and Reactivity
(2021-04-23)The content of this thesis focused on the general syntheses and applications S-substituted alkynyl-, alkenyl- and aryldibenzothiophenium triflates. Addition reactions have been performed from S-alkynyldibenzothiophenium ... -
Selective C–H Activation by Ruthenium(II) Carboxylate and Nickelaelectro-Catalysis
(2021-01-28)This doctoral thesis was divided into two main parts. In the first part, ruthenium(II)-catalyzed ortho-C–H alkynylations of diverse benzoic acids were achieved for the synthesis of aromatic alkynes. And meta-C–H activations, ... -
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 ... -
C–H Activation by Iron(III), Manganese(II) and Rhoda(III)electro Catalysis
(2020-12-15)While major progress was realized with noble transition metal catalysts, the employment of cost-effective and earth-abundant 3d metals has gained significant momentum during the last decade. As stoichiometric amounts of ... -
Iron-Catalyzed C–H/N–H Activations for Annulation of Allenes, Alkynes, and Bicyclopropylidenes
(2020-11-16)Iron-catalyzed C–H/N–H activations for the annulation of allenes, alkynes, and bicyclopropylidenes were realized by using a customizable clickable triazole amide under mild reaction conditions. The powerful iron catalysis ... -
Site-Selectivity in Ruthenium-Catalyzed C–H and C–C Activations
(2020-09-23)During the past decades, transition metal-catalyzed C–H and C–C activation has been recognized as a powerful platform in organic synthesis to access the selective construction of new C–C and C–Het bonds. The full control ... -
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 ...
