Fluorinated Ketene Dithioacetals. 2. Synthesis of 2-Hydroperfluoro Acid Derivatives from Perfluoroketene Dithioacetals
Muzard, Murielle,Portella, Charles
, p. 29 - 31 (1993)
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.
Fluorine gas for life science syntheses: Green metrics to assess selective direct fluorination for the synthesis of 2-fluoromalonate esters

supporting information, p. 3000 - 3009 (2015/05/27)
Optimisation and real time reaction monitoring of the synthesis of 2-fluoromalonate esters by direct fluorination using fluorine gas is reported. An assessment of green metrics including atom economy and process mass intensity factors, demonstrates that the one-step selective direct fluorination process compares very favourably with established multistep processes for the synthesis of fluoromalonates.
Transformation de l'hexafluoropropene en alcool trifluoroallylique, precurseur des α-fluoroacrylates
Nguyen, Thoai,Wakselman, Claude
, p. 273 - 278 (2007/10/03)
The fluoroacryloyl fluoride precursor of α-fluoroacrylic acid esters can arise from an allylic transposition of trifluoroallylic alcohol of which two methods of preparation are presented.In the first, dehydrofluoration of the alcohol CF3CFHCH2OH (4) is used.This alkohol is generated from the ester CF3CFHCOOC2H5 (3).In the second, dehalogenation of the alcohol CF3CFBrCH2OH (10) by zinc is used.The latter is formed by the selective reduction of the ester CF3CFBrCOOC2H5 (9). - Keywords: 2H-Tetrafluoropropanoic acid ester; 2H-Tetrafluoropropanol-1; Trifluoroallylic alcohol; α-Fluoroacryloyl fluoride; NMR spectroscopy
