摘要：

Perfluoroketene dithioacetals were prepared in high yields from perfluoroaldehyde hydrates via their thioacetalization (TiCl4/CH2Cl2) followed by basic phase transfer catalyzed HF elimination. Acidic hydrolysis (CF3CO2H, H2O) and then transesterification (EtOH, Ti(OiPr)4) yielded S-alkyl 2-hydroperfluoro thioesters and ethyl 2-hydroperfluoro esters, respectively.
