unique reaction pathway involving aromatization-driven C–C cleavage to remove the acyl moiety, followed by Cu-mediated oxidative elimination to form an alkene between the α and β carbons. The newly adopted N′-methylpicolinohydrazonamide (MPHA) reagent is key to enable efficient cleavage of ketone C–C bonds at room temperature. Diverse alkyl- and aryl-substituted olefins, dienes, and special alkenes
酮脱氢酰化为烯烃是在温和条件下实现的,它表现出独特的反应途径,包括芳构化驱动的 C-C 裂解以去除酰基部分,然后通过 Cu 介导的氧化消除在 α 和 β 碳之间形成烯烃。新采用的N'-甲基吡啶甲酰肼 (MPHA) 试剂是在室温下有效裂解酮 C-C 键的关键。生成具有广泛官能团耐受性的多种烷基和芳基取代的烯烃、二烯和特殊烯烃。还展示了该方法的战略应用。
