A study on designing a paired electrolysis for electro-induced Michael addition using tetrafluoroborate-based ionic liquid as electrolysis medium and pre-catalyst in a divided cell

Simultaneous double electro-induced synthesis of Michael adducts in both the compartments of a divided cell has been achieved by galvanostatic electrolysis in 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid, exploiting the direct electro-generation of the enolate in the cathodic side and the electro-generation of the Lewis acid BF3 in the anodic side of the cell.
