Air-stable, cationic, Lewis acid, titanocene perfluorooctanesulfonate- catalyzed reductive cleavage of S-S bond by zinc and its application in synthesis of thioesters

摘要

Titanocene perfluorooctanesulfonate is air-stable complex. In the presence of 10mol% of the complex, reductive cleavage of an S-S bond by zinc in commercial tetrahydrofuran at room temperature led to nucleophilic sulfur anion species, which reacted with acid anhydrides to afford thioesters in good to excellent yields.
