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。

Abstract Allyl alkynoic esters were synthesized by the reaction of allyl amines and alkynoic acids via deaminative esterification. The reaction of allyl alkynoic esters with Pd(dba)2 and Xantphos in digylme at 110 °C for 12 h afforded the desired decarboxylated allyl alkynes in good yields. Graphical Abstract
