Copper-catalyzed remote C(sp3)–H azidation and oxidative trifluoromethylation of benzohydrazides

Qian Wang, Jieping Zhu, Xu Bao

The Hofmann-Löffler-Freytag (HLF) reaction is a prototypical example of radical-based remote functionalization of unactivated C(sp3)–H bond. While 1,5-hydrogen atom transfer (1,5-HAT) of the amidyl radical is thermodynamically favorable and is well-establi ...

Axially Chiral Dibenzazepinones by a Palladium(0)-Catalyzed Atropo-enantioselective C-H Arylation

Nicolai Cramer, Matthew Wodrich, Christopher Gordon Newton, Elena Braconi

Atropo‐enantioselective C−H functionalization reactions are largely limited to the dynamic kinetic resolution of biaryl substrates through the introduction of steric bulk proximal to the axis of chirality. Reported herein is a highly atropo‐enantioselectiv ...

Machine learning meets volcano plots: Computational discovery of cross-coupling catalysts

Anne-Clémence Corminboeuf, Benjamin André René Meyer, Anatole von Lilienfeld, Boodsarin Sawatlon

The application of modern machine learning to challenges in atomistic simulation is gaining attraction. We present new machine learning models that can predict the energy of the oxidative addition process between a transition metal complex and a substrate ...

Room temperature decarboxylative cyanation of carboxylic acids using photoredox catalysis and cyanobenziodoxolones: a divergent mechanism compared to alkynylation

Jérôme Waser, Matthew Wodrich, Franck Le Vaillant

The one-step conversion of aliphatic carboxylic acids to the corresponding nitriles has been accomplished via the merger of visible light mediated photoredox and cyanobenziodoxolones (CBX) reagents. The reaction proceeded in high yields with natural and no ...

Pd(0)-Catalysed C-H Functionalisations for the Enantioselective Synthesis of N-Heterocycles

Julia Pedroni

Transition-metal catalysed enantioselective Câ H functionalisations enable rapid increase of molecular complexity via non-classical disconnections. This thesis describes the development of intramolecular Pd(0)-catalysed C-H functionalisations for the asym ...

Enantioselective Total Syntheses of (−)-Rhazinilam, (−)-Leucomidine B, and (+)-Leuconodine F

Jieping Zhu, Qian Wang, Zhengren Xu, Dylan Jean Robert Dagoneau

A divergent total synthesis of three structurally distinct natural products from imine 9 was accomplished through an approach featuring: 1) a Pd-catalyzed decarboxylative cross-coupling, and 2) heteroannulation of 9 with bromoacetaldehyde and oxalyl chlori ...

Rh(III)-Catalyzed C-H Functionalizations as Strategies for Versatile Organic Building Blocks

Van Manh Pham

Transition-metal catalyzed C-H functionalizations have impacted and changed synthetic approaches towards the construction of relevant complex molecules, comprising natural products, active pharmaceutical ingredients, and organic materials. This thesis desc ...

Halide removal from aqueous solution by novel silver-polymeric materials

Urs von Gunten

The objective of this study was to analyze the behavior of a new material, silver-doped polymeric cloth (Ag-cloth), in the removal of bromide and iodide from waters. Silver is immobilized on the cloth, guaranteeing selective adsorption of the halide ions a ...

Catalytic Applications and Mechanistic Investigations of Iron Bis(oxazolinylphenyl)amino Pincer Complexes in Kumada Cross Coupling and Hydrosilylation Reactions

Gerald Bauer

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 ...
