The first example of palladium(II)-catalyzed β-C(sp3)–H iodination of a wide range of ketones using a commercially available aminooxyacetic acid auxiliary has been achieved. This L, X-type directing group overcomes the limitations of the transient directing group approach for C(sp3)–H functionalization of ketones. Practical advantages of this method include simple installation of the auxiliary without
