A new palladium-catalyzed picolinamide (PA)-directed ortho-iodination reaction of epsilon-C(sp(2))-H bonds of gamma-arylpropylamine substrates is reported. This reaction proceeds selectively with a variety of gamma-arylpropylamines bearing strongly electron-donating or withdrawing substituents, complementing our previously reported PA-directed electrophilic aromatic substitution approach to this transformation
