A convenient synthesis of fluoroalkylated γ-butyrolactones from polyfluoroalkyl iodides and 4-pentenoic acid catalyzed by Pd(PPh3)4

A convenient synthesis of fluoroalkylated γ-butyrolactones was realized through the reaction of fluoroalkyl iodides with 4-pentenoic acid in the presence of catalytic amounts of tetrakis(triphenylphosphine)palladium and sequential treatment with triethylamine in 79-85% yields.
