Charakterisierung von Intermediaten in Cobalt-vermittelten Reaktionen
(2019-04-03)Homogeneous catalysis is from outstanding importance for modern chemical synthesis. In addition to palladium- and nickel-based catalyst systems, which are well established for a long time, also cobalt-based catalysts are ... -
Constitution and Reactivity of Palladium Ate Complexes in Cross-Coupling Reactions
(2020-02-18)Palladium-catalyzed cross-coupling reactions are among the most widely used tools for the formation of new carbon-carbon or carbon-heteroatom bonds in organic synthesis. Usually, the intermediates involved in the ... -
Electrospray-Ionization Mass Spectrometry for the Analysis and Quantification of Carbanions
(2023-03-23)The suitability of ESI-MS for the analysis of carbanions was investigated, including the effects of their basicity, concentration and the experimental conditions. This was followed by exemplary applications, such as live ... -
From Copper to Gold: Identification and Characterization of Coinage-Metal Ate Complexes by ESI Mass Spectrometry and Gas-Phase Fragmentation Experiments
(2020-01-09)Organocuprates are important reagents with numerous applications in preparative organic chemistry, which has led to extensive investigations regarding their molecular composition. However, while lithium organocuprates have ... -
Mikroskopische Reaktivität Metallorganischer Spezies
(2023-03-15)In oder to better understand cross-coupling reactions, the oxidative addition between organo halides and organometallates based on iron, cobalt and copper was investigated by using ion-molecule reactions in the gas phase. ... -
Organoferrate als Intermediate in Eisen-Katalysierten Kreuzkupplungsreaktionen
(2019-05-24)In the context of this work a combination of ESI mass spectrometry, mößbauer spectroscopy and electrical conductometry was used to identify and characterize a large number of organoferrates. These anionic species, which ... -
Visible Light-Mediated Metal-Free Photocatalytic Oxidative Reactions and Cycloadditions
(2020-11-16)Currently, there is a strong demand for the development of sustainable chemistry by reducing hazardous substances and using less energy during the process. Hence, ‘Green Chemistry’ or ‘Sustainable Chemistry’ has become the ...
