using hypervalent iodine reagent. A new m-CPBA mediated geminal aminooxygenation is also reported. A novel reagent-switch for the control of migrating group by controlling the two independent geminal addition paths is developed. Deuterium labelling studies and the control studies have provided unambiguous evidences for the phenyl migration and hydride migration in the oxidative geminal difunctionalization
我们在这里报告了使用高价碘试剂进行芳基化的第一个一般方法,以及乙烯基芳烃的无分子间金属化,芳基化的氨基氧化。还报道了新的由m -CPBA介导的双链氨基氧化。开发了一种通过控制两个独立的双链加成路径来控制迁移基团的新型试剂开关。氘标记研究和对照研究提供了明确的证据,证明苯酚和氢化物迁移分别通过半频哪醇重排由PhI(OCOCF 3)2和m -CPBA介导的氧化双子双官能化过程中。
