Aromatic acetals : their synthesis and alkylation
… calcium chloride, ferric chloride, aromatic sulfonic acids, and other. There was no data available comparing the sulfonic acids with the inorganic salts and mineral acids. For that reason one of the subsidiary problems of this investigation was such a comparison.</p><p>In order to investigate …

UNDERSTANDING SULFUR BASED REDOX BIOLOGY THROUGH ADVANCEMENTS IN CHEMICAL BIOLOGY
Sulfenic acids are fleeting intermediates formed from the oxidation of cysteine thiols by a number of biologically relevant oxidants. Sulfenic acids are quickly converted to other species including disulfides, thiosulfinates, sulfinic acids, or sulfonic acids, leading to changes in protein …

Fundamental studies on 2,4,6-trichlorophenyl sulfonate esters
… TCP sulfonates can be synthesised directly from sulfonic acids via activation by triphenylphosphine ditriflate in moderate to excellent yields. These compounds can then be utilised in the synthesis of sulfonamides and suitable conditions for reactions with both simple aliphatic amines and more …

Brønsted Acid Catalyzed Carbon-Carbon Bond Forming Reactions
… compounds. It is foreseen that small molecule sulfonic acids evaluated in this research project will unveil new asymmetric carbon carbon bond forming reactions between substrates hitherto unexplored with Brønsted acid catalysis. It has been established that strong Brønsted acids, such as …

Photochemical processes in engineered aquatic systems for remediation of per- and polyfluoroalkyl substances and algae cultivation
… structures, (e.g., long-chain perfluoroalkyl sulfonic acids (PFSAs) and perfluoroalkyl carboxylic acids (PFCAs)) were readily degraded, other structures (e.g., short-chain PFSAs and fluorotelomer sulfonic acids (FTSs)) were more recalcitrant. Furthermore, results show that PFSAs, PFCAs, and …

Controlling Site-Selectivity in Palladium-Catalysed Cross-Coupling Reactions using Non-Covalent Interactions Between Ligand and Substrate
… electrostatic interaction including carboxylic acids, phosphoric acids, sulfonic acids, and sulfamic acids. Following oxidative addition alkynes (Sonogashira coupling), anilines (Buchwald-Hartwig coupling) and electron-deficient arenes (Fagnou coupling) were all shown to be viable coupling …

Hydroesterification of 1-hexene
… acetate, tertiary phosphines and strong acids such as mineral acids or acids with weak or non-coordinating anions such as sulfonic acids. Although a number of reaction conditions have been reported for homogeneously catalysed transformations of olefins to esters, it has not been clear …
