Abstract

Titanocene perfluorooctanesulfonate is air-stable complex. In the presence of 10 mol% 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.
