Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Toluene | HCID 1140 | — |
| Reactant | 2,2-Dibromopropane | HCID 11658 | — |
| Reactant | Triphenylphosphine | HCID 11776 | — |
| Product | (3-Bromopropyl)-triphenylphosphonium bromide hydrobromide | HCID 19897085 | — |
Reaction Steps
In this example, 350.0 g of triphenylphosphine and 270.0 g of dibromopropane are suspended in 700 ml of toluene and the suspension is heated at reflux for 25 hours. After allowing the suspension to stand for cooling, the formed product is separated by filtration and washed with 2 l of toluene to obtain 550.0 g of (3-bromopropyl)-triphenylphosphonium bromide hydrobromide having m.p. 233-234° C.
