Photochemical oxidation of phenols and anilines mediated by phenoxyl radicals in aqueous solution

Urs von Gunten, Stephanie Christa Remke

Reactive intermediates formed upon irradiation of chromophoric dissolved organic matter (CDOM) contribute to the degradation of various organic contaminants in surface waters. Besides well-studied "short-lived" photo oxidants, such as triplet state CDOM (3 ...

Cu(I)-Catalyzed gem-Aminoalkynylation of Diazo Compounds: Synthesis of Fluorinated Propargylic Amines

Jérôme Waser, Guillaume Dominique Pisella, Nieves Pilar Ramirez Hernandez

The gem-aminoalkynylation of fluorinated diazo compounds catalyzed by a simple Cu(I) salt is described. This three-component reaction allows the synthesis of propargylic amines with broad functional group tolerance. Both electron-rich and electron-poor ani ...

The Photoisomerization Pathway(s) of Push‐Pull Phenylazoheteroarenes

Anne-Clémence Corminboeuf, Sergio Vela Llausi

Azoheteroarenes are the most recent derivatives targeted to further improve the properties of azo‐based photoswitches. Their light‐induced mechanism for trans‐cis isomerization is assumed to be very similar to that of the parent azobenzene. As such, they i ...

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 ...

Preparation of cationic azo compounds

Kay Severin, Alexander Tskhovrebov

The present invention relates to a novel method for preparing cationic azo compounds, which preferably can be used as dyes. Further, the invention relates to novel cationic azo compounds and the use of N2O in the synthesis of azo-imidazolium dyes. ...

Rationalizing Fluorescence Quenching in meso-BODIPY Dyes

Anne-Clémence Corminboeuf, Alberto Fabrizio, Antonio Prlj

meso-Substituted boron-dipyrromethene (BODIPY) dyes are a puzzling class of molecules, which feature contrasting emissive behaviors. The full mechanistic picture for these distinctive properties is still missing. Using static and dynamic excited state comp ...
