Catalytic dimerization of alkyl acrylates |
| abstract |
Alkyl acrylates are catalytically dimerized, e.g., to produce alkyl diesters of dihydromuconic acid, in the presence of a catalytically effective amount of palladium, tetrafluoroboric acid and a hydrogenophosphonium tetrafluoroborate, and wherein the palladium concentration ranges from 0.1 to 3 mmol per mole of said at least one alkyl acrylate, the reaction temperature ranges from 70 DEG to 150 DEG C. and the hydrogenophosphonium tetrafluoroborate concentration is at least 6 mmol per mole of said at least one alkyl acrylate. |
