Fluorinated Stannanes. Part 2. The Stereospecific Synthesis of Fluorinated Stannanes via a Barbier‐Type Reaction Between Fluorinated Halides and Tributyltin Chloride Mediated by Zinc or Cadmium.

Abstract

Abstract Fluorinated stannanes are valuable synthons in synthetic organofluorine chemistry. Fluorinated vinyl, alkyl and aryl halides reacted efficiently with tri- n -butyltin chloride in the presence of zinc or cadmium to yield the corresponding stannanes in good yields. In some cases, yield of the stannanes showed a dramatic improvement over the transmetalation method. In all other cases, comparable yields were obtained.
