A series of 1-fluoroalkyl carboxylate derivatives was synthesised by reacting a carboxylic acid and a ketone or aldehyde with (diethylamino)sulfurtrifluoride (DAST). The reactivity of these compounds towards the nucleophiles benzylamine and water was investigated. The hydrolysis of the 1-fluoroalkyl carboxylates by an esterase was observed, along with the concomitant release of the fluoride ion, demonstrating

Levulinic acid and related γ-ketoacids react with diethylaminosulfur trifluoride to give γ-fluorobutyrolactones in good yield. The involvement of a bicyclic (3.2.1) mechanism is considered.
