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 ... -
Selectivity Control in 3d Transition Metal-Catalyzed C–H Activation
(2019-08-23)Methods for the selective functionalization of otherwise inert C–H bonds have been recognized as a transformative tool in synthetic organic chemistry, with applications ranging from the synthesis of complex bioactive ... -
Cobalt(III)- and Manganese(I)-Catalyzed C-H and C-C Activations
(2019-03-28)Metal-catalyzed C─H and C─C functionalizations have become an increasingly viable approach, which allows the direct formation of C─C and C─heteroatom bonds in an atom- and step-economical manner. However, the significant ... -
Studien zur oxidativen Funktionalisierung von Alkenen mittels Selen-pi-Säure-Katalyse
(2019-01-24)The application of diselenides as catalysts for the oxidative functionalization of alkenes via selenium-pi-acid catalysis was researched. Besides a method for the diselenide-catalyzed formation of indoles relying on NFSI ... -
New Methodologies for the Regio- and Stereoselective Electrophilic Cyanation of Alkynes
(2019-01-04)The ability of sulfur imidazolium thiocyanates salts to serve as a remarkable source of cyano groups was tested, thus efficiently promoting cyanations of internal and terminal alkynes. The methods described are performed ... -
Ruthenium- and Cobalt-Catalyzed C-H Activation
(2018-11-12)The thesis contents methods for the ruthenium- and cobalt catalyzed C-H activation of arenes. Ruthenium(II) catalysis was used to alkenylate arylacetamides using acrylates or alkynes. Further, ruthenium-catalyzed C-H ... -
