  Selectiveortho-Bromination of Substituted Benzaldoximes Using Pd-Catalyzed C–H Activation: Application to the Synthesis of Substituted 2-Bromobenzaldehydes

  摘要：

  Substituted 2-bromobenzaldehydes were synthesized from benzaldehydes using a three-step sequence involving a selective palladium-catalyzed ortho-bromination as the key step. O-Methyloxime serves as a directing group in this reaction. A rapid deprotection of substituted 2-bromobenzaldoximes afforded substituted 2-bromobenzaldehydes with good overall yields.
