Manganese-Mediated Reductive Transamidation of Tertiary Amides with Nitroarenes

Xile Hu, Chi Wai Cheung

Amides are an important class of organic compounds, which have widespread industrial applications. Transamidation of amides is a convenient method to generate new amides from existing ones. Tertiary amides, however, are challenging substrates for transamid ...

Decarboxylative C(sp3)–N cross-coupling via synergetic photoredox and copper catalysis

Xile Hu, Adrian Frey, Jonathan Balon, Runze Mao

Amines are a quintessential moiety in bioactive molecules, pharmaceuticals and organic materials. Transition-metal-catalysed C–N coupling of aryl electrophiles has been established as a powerful and reliable method for amine synthesis. However, the analogo ...

Development of heterogeneous catalytic systems for the transformation of carbon dioxide to methanol under mild conditions

Aswin Gopakumar

Rising level of carbon dioxide (CO2) is a significant contributor to global warming and poses a major concern in modern society and environment. Anthropogenic activities such as fossil fuel combustion, cement production and deforestation are the primary ca ...

Dyes, Radicals and Nitrous Oxide Adducts Derived from N-Heterocyclic Carbenes

Léonard Yannick Maurice Eymann

N-Heterocyclic carbenes are able to form covalent adducts with nitrous oxide (N2O) under ambient conditions. This thesis summarizes the studies of these adducts and their reactivity. A ditopic carbanionic N-heterocyclic carbene was found to react with nit ...

Investigations of the Chemistry of 1-Alkynyltriazenes

Florian Gérald Abela

The chemistry of aromatic triazenes is well known, and has been explored for more than a century. These compounds have emerged as very useful intermediates, because of their unique reactivity. This functionality can notably be used to access many other fun ...

Au Core-Pd Shell Bimetallic Nanoparticles Immobilized within Hyper-Cross-Linked Polystyrene for Mechanistic Study of Suzuki Cross-Coupling: Homogeneous or Heterogeneous Catalysis?

Lioubov Kiwi, Thomas La Grange

The synthesis of catalytically active bimetallic Au-Pd nanoparticles stabilized in hyper-cross-linked polystyrene (HPS) for Suzuki cross-coupling of 4-bromoanisole (4-BrAn) and phenylboronic acid is presented. The core-shell structure with a thin (less tha ...

Cross-Coupling of Alkyl Redox-Active Esters with Benzophenone Imines: Tandem Photoredox and Copper Catalysis

Xile Hu, Jonathan Balon, Runze Mao

Alkyl amines are an important class of organic compounds in medicinal and materials chemistry. Until now very have been very few methods for the synthesis of alkyl amines by metal‐catalyzed cross‐coupling of alkyl electrophiles with nitrogen nucleophiles. ...

Mechanistic Study of the N-Formylation of Amines with Carbon Dioxide and Hydrosilanes

Gabor Laurenczy, Paul Joseph Dyson, Martin Hulla

N-formylation of amines with CO2 and hydrosilane reducing agents proceeds via fast and complex chemical equilibria, which hinder easy analysis of the reaction pathways. In situ reaction monitoring and kinetic studies reveal that three proposed pathways, vi ...

Direct amidation of esters with nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Esters are one of the most common functional groups in natural and synthetic products, and the one-step conversion of the ester group into other functional groups is an attractive strategy in organic synthesis. Direct amidation of esters is particularly ap ...

Nickel-Catalyzed Reductive Transamidation of Secondary Amides with Nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Transmidation is an attractive method for amide synthesis. However, transamidation of secondary amides is challenging. Here, we describe a reductive transamidation method that employs readily available nitro(hetero)arenes as the nitrogen sources, zinc or m ...
