WebFeb 15, 2016 · Heavy metal ions are highly toxic and widely spread as environmental pollutants. New strategies are being developed to simultaneously detect and remove these toxic ions. Herein, we take the intrinsic advantage of covalent organic frameworks (COFs) and develop fluorescent COFs for sensing applications. As a proof-of-concept, a thioether … WebThe chemistry of thioether bond formation is poorly under-stood (2). Very little is known regarding the chemical processes taking place during cytochrome c maturation in vivo (1). In our previous work, we have reported the first in vitro formation of a c-type cytochrome containing two thioether bonds (4). It was

WebKOH promotes an unusual deoxidative coupling reaction of β-sulfinyl esters with benzylic trimethylammonium salts to produce thioethers. Enantiomerically enriched quaternary ammonium salts provide benzyl thioethers with clean inversion of the configuration. Q. Zhang, H. Feng, F. Chen, Z. He, Q. Zeng, J. Org.
