A palladium‐catalyzed oxygenative cross‐coupling of ynamides and benzyl bromides has been developed. After subsequent hydrogenation, α,α‐disubstituted amide derivatives were obtained in good yields. Migratory insertion of α‐oxo palladium carbene species, generated by intermolecular oxidation, is proposed as the key step in this reaction. The study demonstrates the potential of ynamides to serve as
已经开发了钯催化的酰胺和苄基溴的氧交叉偶联。在随后的氢化之后,以高收率获得了α,α-二取代酰胺衍生物。分子间氧化产生的α-氧代钯卡宾物种的迁移插入被认为是该反应的关键步骤。这项研究表明,在钯催化的C-C键形成交叉偶联反应中,乙酰胺具有作为卡宾前体的潜力。
