The reactivities of the F-tert.-alkyl halides (CF3CF2CF2(CF3)2CX (1a-c: X = I, Br Cl)) towards the corresponding lithium halides LiY (2a-c: Y = I, Br, Cl), in acetonitrile, reflect the electron acceptor properties of compounds 1 and the donator strength of the anions Y(1-).The tertiary carbanion F-2-methylpentanide acts as the key intermediate in the formation of the main products (F-2-methyl-2-pentene, F-2-methyl-1-pentene and F-2-hydro-2-methylpentane), and also of the halide substitution products obtained from 1a.No support for the participation of any perfluoroalkyl radical could be found.
