Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methyl p-toluenesulfonate | HCID 6645 | — |
| Reactant | Triphenylphosphine | HCID 11776 | — |
| Product | Methyltriphenylphosphonium p-toluenesulfonate | HCID 18401301 | 98.7% |
Reaction Steps
A mixture of 11.8 g (45.0 mmol) of triphenylphosphine and 8.40 g (45.1 mmol) of methyl tosylate was allowed to react for 2 hr at 130° C. A total of 19.9 g (44.4 mmol, 98.6%) of methyltriphenylphosphonium tosylate was obtained. This was further purified by stirring overnight in 95:5 ether-acetonitrile. Analyses: mp 147.0°-149.0° C.
