Sulfadiazine (SD) and sulfamethoxazole (SMX) are widely used sulfonamide antibiotics, which are present as contaminants in surface waters and are known to undergo phototransformation. This kinetic study was conducted to identify the processes responsible f ...
New conditions have been found for the desulfitative Mizoroki-Heck arylation and trifluoromethylation of mono- and disubustituted olefins with arenesulfonyl and trifluoromethanesulfonyl chlorides. Thus (E)1,2-disubstituted alkenes with high stereoselectivi ...
The potential of chlorine dioxide (ClO2) for the oxidation of pharmaceuticals during water treatment was assessed by determining second-order rate constants for the reaction with selected environmentally relevant pharmaceuticals. Out of 9 pharmaceuticals o ...
The present invention relates to a process for preparing sulfonyl halides comprising the steps of a) reacting an enoxymetal, allylsilane or allylstannane compound, preferably in the presence of a diene, with sulphur dioxide and b) adding a suitable halogen ...
The goal of this thesis was to open a new route to the synthesis of conjugated trienes using a new SO2-based C-C bond forming reactions developed in Lausanne. In addition, the potential of SO2 for applications in synthetic organic chemistry has been exploi ...
Sulfonamide antibiotics are an important class of organic micropollutants in the aquatic environment. For several, sulfur dioxide extrusion products have been previously reported upon photochemical or dark oxidation. Using quantum chemical modeling calcula ...
The introduction of sulfa drugs for the chemotherapy of bacterial infections in 1935 revolutionized medicine. Although their mechanism of action is understood, the molecular bases for most of their side effects remain obscure. Here, we report that sulfamet ...
Radicals play an important role in many areas of chemistry, such as atmospheric, aquatic, polymer, and biological, to name a few. Radicals are often highly reactive species which are short-lived and therefore harder to study by experimental techniques. In ...
RNA plays key roles in essential biological processes, such as protein synthesis, transcriptional regulation, splicing and retroviral replication. The structural diversity of RNA molecules and the lack of known RNA repair mechanisms make these biopolymers ...
The goal of this thesis was to find conditions to form C-C double bond and single bond using sulfonyl derivativies, which are arising from the Vogel's oxyallylation cascades. In a second chapter, it is shown that 2-methylprop-2-ene-1-sulfonyl fluorides can ...
