alcohol were used as precursors for the preparation of the appropriate bis(polyfluoroalkoxymethyl)carbinols [(RFHOCH2)2CHOH, 1a–c, RFH = (a) CF3CH2, (b) (CF3)2CH, and (c) (CF3)3C] and the corresponding mesylates [(RFHOCH2)2CHOSO2CH3, 2a–c]. This novel design paradigm is introduced to eliminate the persistence and bioaccumulation problems of fluorous chemistry, which are associated with the use of longer
