demonstrate that the scope of our electron transfer initiated cyclization reaction can be significantly broadened by exploiting the relationship between the oxidation potentials of homobenzylic ethers and the mesolytic benzylic carbon-carbon bond dissociation energies of their radical cations. By lowering the oxidation potential of the electrophore and the benzylic carbon-carbon bond dissociation energy, we
在这次交流中,我们证明了我们的电子转移引发的环化反应的范围可以通过利用高苄基醚的氧化电位与其自由基阳离子的中分解苄基碳-碳键解离能之间的关系来显着拓宽。通过降低电泳的氧化电位和苄基碳-碳键解离能,我们可以在温和的非光化学条件下引发反应。芳烃氧化的选择性和温和的反应条件使得各种富电子烯烃作为亲核基团以优异的效率形成碳-碳键。
