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.
