Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Butanedioic acid, 2-methyl-, 1,4-dimethyl ester | HCID 15350 | — |
| Catalyst | Rhodium | HCID 23948 | — |
| Product | Dimethyl itaconate | HCID 69240 | — |
Reaction Steps
The hydrogenation is carried out by a method similar to example G2 using the rhodium complex of example F5. The conversion is quantitative, and the optical yield ee of the hydrogenation product (dimethyl methylsuccinate) is greater than 98%.
