Alkylation of perfluoro-2-methyl-2-pentylcarbanion with alkyl and allyl halides

Add time:08/10/2019    Source:sciencedirect.com

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 occurred. The reaction with 1-iodo-3,3,3,-trifluoropropene resulted in the formation of 3,3,3,-trifluoropropene and 2-H-perfluoro-2-methyl-pentane.
