A new one-pot synthesis of difluoro(organylsulfinyl)acetic acid esters

A novel single-step method for the synthesis of esters of difluoro(organylsulfinyl)acetic acids, by reacting aromatic compounds with isopropyl chlorosulfinyldifluoroacetate, was developed. The feasibility of transforming the sulfoxide intermediates into corresponding sulfides and sulfones was demonstrated.
