| | BUTYLZINC BROMIDE Usage And Synthesis |
| Uses | Butylzinc bromide is an organozinc compound, which can be used as a reagent:
- In palladium-catalyzed Negishi cross-coupling reaction to construct carbon-carbon bond by reacting with organic halides or triflates.
- To prepare n-butylanisole by treating with 4-bromoanisole in the presence of a tetraphosphine ligand and a palladium catalyst.
