Abstract

Abstract The reactivities of the F-tert.-alkyl halides (CF 3 CF 2 CF 2 (CF 3) 2 CX (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−. 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- ...
