1synthesis methods
- Product Name:PROPARGYLTRIPHENYLPHOSPHONIUM BROMIDE
- CAS Number:2091-46-5
- Molecular formula:C21H18BrP
- Molecular Weight:381.25
Propargyltriphenylphosphonium bromide is readily available from Triphenylphosphine and propargyl bromide (see Propargyl Chloride) (eq 1). The presence of hydrogen bromide is absolutely necessary, otherwise the base Ph3P causes the formation of tarry products.
Yield: 75.6%
Reaction Conditions:
with hydrogen bromide in 1,4-dioxane at 20; for 0.833333 h;
