Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hexanoic acid, 4,6,6,6-tetrachloro-3,3-dimethyl-, ethyl ester | HCID 108412 | — |
| Reactant | Ethyl 4-bromo-6,6,6-trichloro-3,3-dimethylhexanoate | HCID 12607835 | — |
| Product | 2(3H)-Furanone, 5-(2,2-dichloroethenyl)dihydro-4,4-dimethyl- | HCID 10198203 | 90% |
Reaction Steps
The procedure of Reference Example 1 was repeated except that 35.4 parts of ethyl 3,3-dimethyl-4-bromo-6,6,6-trichlorohexanoate was used in lieu of ethyl 3,3-dimethyl-4,6,6,6-tetrachlorohexanoate. By this procedure was obtained 19.0 parts of 3,3-dimethyl-4-(2',2'-dichlorovinyl)-4-butanolide (yield 90%).
