Article abstract of DOI:10.1016/S0022-1139(00)81980-6

Perfluoro-2-methyl-2-pentylcarbanion, generated from perfluoro-4-methyl-2-pentene in an aprotic solvent, reacted with halides RX, where R = alkyl or allyl and X = I, Br, or Cl, to give fluorohydrocarbons of the general formula CF3CF2CF2C(CF3)2R.No reaction with iso-propyl iodide and with 1-iodo-2,2,2-trifluoroethane occured.The reaction with 1-iodo-3,3,3-trifluoropropane resulted in the formation of 3,3,3-trifluoropropene and 2-H-perfluoro-2-methylpentane.
