2-Hydroaldehydes, RfCH (R) CHO, where Rf= CF3, C2F5, n-C3F7 and R= CF3, C2F5, n- C3F7, Ph, H, were prepared via acid hydrolysis of the corresponding vinyl ethers, RfC (R)= CHOCH3, which can be readily prepared by reaction of [Ph3P+ C¯ HOCH3] with the corresponding ketone. The 2-hydroaldehydes can be chemoselectively converted to the acyl halide, RfCH (R) C (O) X (X= Cl, Br), via free-radical halogenation. The perfluoroalkyl ...
