Pd(II)-catalyzed ortho C-H acetoxylation of triflate protected phenethyl- and phenpropylamines has been achieved with tert-butyl peroxyacetate as the stoichiometric oxidant and either DMF or CH3CN as the promoter. The reaction was found to tolerate a large variety of functional groups and could be combined with subsequent intramolecular amination to afford functionalized indoline derivatives.
