Abstract
English
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 oxygenation of arylacetamides was developed. Moreover, an efficient cobalt catalyst for the direct Hiyama-type C–H arylation of beazamides with organosilanes is shown. Finally, a cobalt-catalyzed C−H/C−C functionalization of arenes with vinylcyclopropanes was developed.
