Sulfides tethered to oxazolines function as effective ligands for palladium catalysed allylic substitution, affording good to excellent levels of enantioselectivity (56 to >96% ee). Both the tether length between the nitrogen and sulfur atoms and also the nature of the sulfide have been shown to affect the performance of these ligands
