Enzymatic hydrolyses of the σ-symmetric dicarboxylic diesters bearing a sulfinyl group as the prochiral center were examined by employing porcine liver esterase and procine pancreatic lipase. Eventually, their chiral half esters were elaborately obtained as the corresponding chiral phenacyl esters. The stereochemistry of the chiral half esters was determined by the X-ray analysis and their chemical correlations.

The synthesis of fluorocompounds by sulfide electrochemical oxidation using Et3N.3HF as fluorinating agent is described. Chemical oxidation (DBH) is less efficient.
