Development of Catalytic Asymmetric C-H Functionalizations with Chiral Cyclopentadienyl Iridium(III) Complexes

Cp*Ir(III) catalyzed C-H functionalization is a growing field, since it provides novel complementary reactivities, but enantioselective C-H functionalization reactions with this metal remain a niche. This thesis investigates CpXIr(III) catalyzed asymmetric ...

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, Jennifer Kuziola

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 ...

Operando XAS study of the influence of CO and NO on methane oxidation by Pd/Al2O3

Davide Ferri, Oliver Kröcher, Anton Petrov

Methane oxidation on Pd/Al2O3 has been investigated using operando X-ray absorption spectroscopy (XAS) at the Pd K-edge. The influence of CO and NO on methane abatement has been addressed performing temperature programmed reaction runs while recording simu ...
