Challenging substrates and conditions in homogeneous catalysis pose stringent demands on the ligands used. A novel, bulky, 1-adamantyl-substituted disulfoxide ligand designed after a systematic evaluation of the electronic and steric properties of disulfoxide substituents permits the allylic oxidative C-N coupling reaction to proceed at lower catalyst loading while requiring a smaller excess of reagents. Additionally, this ligand improves the yields when TsNHCOOCH2CCl3, a novel reagent that permits deprotection of the products under both acidic and basic conditions, is used.

(Chemical Equation Presented) O2-coupledallylic C-H amination: A first general palladium-mediated intermolecular aerobic oxidative allylic amination was developed to synthesize linear (E)-allylimides with high regioselectivity (see scheme; MA = maleic anhydride). The proposed mechanism involves an allylic C-H activation with subsequent nitrogen nucleophile substitution. The catalytic system allows efficient dioxygen-coupled turnover without additional cocatalysts.
