Application

Tributyltin chloride (Bu3SnCl or tri-n-butylstannane) is an organotin compound that can be used as a reagent for:
  • The synthesis of fluorinated stannanes by reacting with fluorinated alkyl, aryl or vinyl halides using Zn or Cd catalyst via Barbier-type reaction.
  • The preparation of γ-hydroxyvinylstannanes, and indol-2-yltributylstannane.
  • The conversion of organozirconiums to organostannanes.
