Iron(III) bisoxazolinylphenylamido (bopa) pincer complexes are efficient precatalysts for the cross-coupling of nonactivated primary and secondary alkyl halides with phenyl Grignard reagents. The reactions proceed at room temperature in moderate to excelle ...
Cross-coupling reactions of non-activated alkyl halides are potentially useful chemical transformations. At the same time, however, they are challenging due to a series of unproductive side reactions. Recently, significant progress has been made to overcom ...
The chemical activation of nitrous oxide (N2O) can be achieved by organocalcium, organosodium, and organolithium compounds. Grignard reagents, on the other hand, are believed to be inert. We demonstrate that this generalization is not correct. Some aliphat ...
Many nickel-based catalysts have been reported for cross-coupling reactions of nonactivated alkyl halides. The mechanistic understanding of these reactions is still primitive. Here we report a mechanistic study of alkyl-alkyl Kumada coupling catalyzed by a ...
Transition-metal-catalyzed C-C coupling reactions have been extensively studied in the past three decades. These reactions have become invaluable to fundamental research and industrial applications, because they can be used construct complicated molecules ...
Within the last decades the transition metal-catalyzed cross-coupling of non-activated alkyl halides has significantly progressed. Within the context of alkyl-alkyl cross-coupling, first row transition metals spanning from iron, over cobalt, nickel, to cop ...
Catalysis with laughing gas: N2O in combination with transition-metal catalysts allow the oxidative homo- and cross-coupling of Grignard reagents. The reactions can be performed under mild conditions despite the inert character of N2O. ...
This dissertation is devoted to the development of well-defined nickel complexes as catalysts for cross coupling processes of alkyl electrophiles. In chapter one, we summarize recent cross coupling methodologies of alkyl electrophiles using nickel based ca ...
The aim of the project was to investigate iron bis(oxazolinylphenyl)amino (bopa) pincer complexes as pre-catalysts in the enantioselective Kumada cross-coupling of non-activated alkyl halides with aryl Grignard reagents. From this preliminary cross-couplin ...
This thesis describes novel methods for and investigations into C–C and C–N bond formation reactions. Chapter 1 gives a very brief overview of established strategies for the formation of new C–C bonds in organic synthesis. In chapter 2, a multi‐step one‐po ...
