1,2-Dichlorobenzene → 2,6-Dichlorobenzoxazole
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1,2-Dichlorobenzene | HCID 7239 | — |
| Reactant | 6-Chloro-2,3-dihydrobenzoxazol-2-one | HCID 29858 | — |
| Product | 2,6-Dichlorobenzoxazole | HCID 77175 | — |
Reaction Steps
lf the process is carried out as in Example 1, but only 500 ml of o-dichlorobenzene is initially introduced, and the 6-chlorobenzoxazolin-2-one is metered in as a suspension in 500 ml of o-dichlorobenzene, then 2,6-dichlorobenzoxazole is obtained in the same yield and purity as in Example 1.
