Recycling of allylic alkylation Pd catalysts containing phosphine-imidazoline ligands in ionic liquidsElectronic supplementary information (ESI) available. See DOI: 10.1039/c2gc35732a

An efficient catalytic system to perform allylic alkylation in ionic liquids based on a Pd/phosphine imidazoline system has been designed. This system affords very good results (ee's up to 95%) when used with the appropriate ionic liquid as well as under microwave conditions. Recycling experiments were conducted showing very promising results. An efficient catalytic system to perform allylic alkylation in ionic liquids based on a Pd/phosphine-imidazoline system has been designed.
