mediated formation of C-C bonds from benzylicC(sp3 )-H bonds adjacent to an oxygen or nitrogen atom by dehydrogenativecoupling with enolizable carbonyls has been developed. The use of these oxidants in combination with catalytic amounts of Fe(OTf) 2 as Lewis acid allows the reaction to be carried out under mild conditions, leading to the corresponding coupling products in moderate to good yields
通过与可烯醇化羰基的脱氢偶联,由与氧或氮原子相邻的苄基 C(sp 3 )-H 键介导的第一种氧代铵盐介导形成 CC 键。这些氧化剂与作为路易斯酸的催化量的 Fe(OTf) 2 结合使用允许反应在温和的条件下进行,从而以中等至良好的产率产生相应的偶联产物。

Oxidative Alkylation of Cyclic
Benzyl Ethers with Malonates and Ketones Using Oxygen as the Terminal
Oxidant
A simple oxidative alkylation of cyclic benzylethers with malonatesand ketones was developed using a mixture of Cu(OTf) 2 ,InCl 3 , and NHPI as catalyst under an atmospheric pressureof oxygen.
