Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Bromo-4-chlorophenol | HCID 69670 | — |
| Reactant | 2-(2-Bromo-4-chlorophenoxy)-acetaldehyde diethyl acetal | HCID 22144797 | — |
| Product | 7-Bromo-5-chloro-1-benzofuran | HCID 22144720 | — |
Reaction Steps
Beginning with 25 gm (120.5 mmol) 2-bromo-4-chlorophenol, 41.16 gm crude 2-(2-bromo-4-chlorophenoxy)-acetaldehyde diethyl acetal was prepared essentially as described in Preparation IV. A sample of this crude material was subjected to silica gel chromatography to provide an analytical sample.
