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.

Phosphinoimidazoline (PHIM) ligands bearing a triazolylmethyl substituent at the sp3 nitrogen atom in the imidazoline ring lead to highly improved enantioselectivity (up to 99% ee) in allylic substitution reactions with respect to analogous ligands with substituents lacking the triazole unit. NMR and theoretical studies support a shift in the coordination mode of the PHIM ligand to palladium, triggered by a very favourable interaction with the triazole unit. Copyright
