Abstract

IrI-catalyzed allylic alkylations of linear aryl-substituted allylic acetates proceed with enantiomeric excess of up to 95% ee using bidentate phosphinooxazolines as chiral ligands. The chiral (π-allyl)IrIII complexes 14 and 15 have been characterized by X-ray crystal structure analysis and spectroscopic data. The stoichiometric reaction between sodium dimethyl malonate and complex 14 proceeded with nucleophilic addition at the central allylic carbon as well as ligand exchange at Ir to give the iridacyclobutane complex 16, which was fully characterized. Complex 16 was transformed into (π-allyl)IrIII complexes by treatment with Lewis acid or iodine.
