Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Propanedioic acid, dibutyl ester | HCID 136925 | — |
| Reactant | 1,4-Dichloro-2-butene, (2E)- | HCID 642197 | — |
| Product | Di-n-butyl 2-vinylcyclopropane-1,1-dicarboxylate | HCID 20504385 | 69% |
Reaction Steps
Example 3 was repeated except the organic solvent was omitted and the mol ratio of trans 1,4-dichlorobutene-2 to di-n-butyl malonate was 2:1. Di-n-butyl 2-vinylcyclopropane-1,1-dicarboxylate was obtained in 69% yield.
