Conclusions 1. α,β-Unsaturated β-polyfluoroalkylketones and β-polyfluoroalkyl-α,β-epoxyketones react with 2,4-bis(4′-methoxyphenyl)-2,4-dithioxo-PV,PV-1,3,2,4-dithiadiphosphetane in refluxing acetonitrile, toluene, or xylene to form the corresponding 3-alkyl-or 3-aryl-5-polyfluoroalkyl-1, 2-dithiolenes-3. 2. The reaction of epoxychalcone with this reagent at 50°C or upon heating at reflux in toluene gives the epoxide ring opening product, 5-benzoyl-2-(4′-methoxyphenyl)-4-phenyl-2-thioxo-1, 3,2-oxathiaphospholane.
