Hydrochloric Acid → 1,1-Bis(4-pyrrolidinophenyl)ethylene
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | 1,1-Bis(4-pyrrolidinylphenyl)ethane | HCID 13766085 | — |
| Product | 1,1-Bis(4-pyrrolidinophenyl)ethylene | HCID 3296021 | 50% |
Reaction Steps
In the same manner as in 1-2 of Example 1 except for using the thus obtained 1,1-bis(4-pyrrolidinylphenyl)ethane instead of 1,1-bis(4-dimethylaminophenyl)ethane and using hydrochloric acid instead of nitric acid in 1-2 of Example 1, 1,1-bis(4-pyrrolidinylphenyl)ethylene (m.p. 211° C.) was obtained in a yield of about 50%.
