Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Aniline | HCID 6115 | — |
| Reactant | p-Toluidine | HCID 7813 | — |
| Reactant | 4-Fluoroaniline | HCID 9731 | — |
| Reactant | Tetra-n-butylammonium tribromide | HCID 23500184 | — |
| Product | 2-Bromo-4-methylaniline | HCID 11422 | 66% |
Reaction Steps
To show that selectivity is still obtained using a highly activated aniline, bromination of p-toluidine using tetrabutylammonium tribromide was carried out as generally described in Example 4, but substituting p-toluidine for 4-fluoroaniline, on a 0.75 mole reaction. The desired product 2-bromo-4-methylaniline was obtained in 66% yield on the 0.75 mole reaction.
