A novel palladium-catalyzed cyclization−oxidation sequence yielding bicyclo[3.1.0]hexanes was developed. A mechanism involving a Pd(II)/Pd(IV) cycle was proposed. An SN2 C−O bond formation from an alkyl−palladium(IV) intermediate was also suggested.
开发了一种新的钯催化环化氧化序列,产生双环 [3.1.0] 己烷。提出了涉及 Pd(II)/Pd(IV) 循环的机制。还建议从烷基-钯(IV)中间体形成 SN2 CO 键。
