arylhydrazines and anilines via radical arylation reactions under simple oxidative conditions. The strong directing effect of the free and unprotonated amino functionality leads to high regioselectivities, and anilines have been shown to be significantly better aryl radical acceptors than nitrobenzenes or phenyl ethers. The methodology is also applicable to phenols, which react best as phenolates under
取代的2-氨基联苯已由芳基肼和苯胺在简单的氧化条件下通过自由基芳基化反应制得。游离的和未质子化的氨基官能团的强引导作用导致高的区域选择性,并且苯胺已被证明是比硝基苯或苯基醚更好的芳基自由基受体。该方法还适用于在强碱性条件下以酚盐形式反应最好的酚。最后,苯胺和苯胺盐在各种条件下的自由基芳基化反应首次证明,还可以通过重新芳构化步骤来控制区域选择性,并且向取代的苯中添加芳基甚至是可逆的。
