Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Dimethyl malonate | HCID 7943 | — |
| Reactant | 1,4-Dichloro-2-butene, (2E)- | HCID 642197 | — |
| Product | 1,1-Dimethyl 2-ethenylcyclopropane-1,1-dicarboxylate | HCID 10464992 | — |
Reaction Steps
The procedure of Example 2 was followed except that trans-1,4-dichlorobutene-2 as obtained by the procedure of Example 4 was condensed with dimethyl malonate. High yields of dimethyl 2-vinylcyclopropane-1,1-dicarboxylate of high purity were obtained.
