In summary, a novel Pd-containing oxidative addition complex (OAC-1) has been developed and applied to aminations of aryl fluorosulfates in water using aqueous micellar media derived from a biodegradable surfactant, Savie. DFT calculations on OAC-1 match the X-ray structure, with p-complexation of the Pd to one of the heterocycle rings in the ligand. The calculations also show that three conformations of the phenyl and t-butyl ligand substituents are 20% isolated more stable than the conformation of the X-ray structure in the solid state, consistent with the NMR spectra. This homogeneous catalysis technology relies on low loadings of precious metal, and offers several advances in sustainability, including:
