The excess acidity method has been applied to hydrolysis rate data, obtained as a function of medium composition, for four thiobenzoic acids, thioacetic acid, eight ethyl thiolbenzoates, and eight ethyl thionbenzoates in aqueous sulfuric acid. The mechanistic behaviour thus revealed has both similarities to and differences from that of a typical ester like ethyl benzoate, which gives benzoic acid by

development of an iron(III)-catalyzed coupling of thioesters with aliphatic organomanganese reagents. The good functional group tolerance resulted in successful transformation of a range of thioesters, including biologically relevant compounds. The presence of accessible β-hydrogen atom in the organomanganese reagent seems crucial for an effective catalyst activation. The liberated thiolate stabilizes the
