(4-R)phenols by primary and secondary anilines was developed. Depending on the identity of the R group, the products of this efficient reaction are either benzoquinone anils (C-N coupling) that are produced via a sequential oxidative amination/dehydrogenation (R = H), oxidative amination/elimination (R = OMe) steps, or N,O-biaryl compounds (C-C coupling) that are formed when R = alkyl through an oxidative
开发了铁和锰催化的伯胺和仲苯胺对(4-R)酚的对位选择性氧化胺化反应。根据R基团的身份,此有效反应的产物是苯醌醌(CN偶联),它是通过顺序氧化胺化/脱氢(R = H),氧化胺化/消除(R = OMe)步骤产生的,或N,O-联芳基化合物(CC偶联),当R =烷基时,是通过氧化胺化/ [3,3]-σ重排(奎宁胺重排)过程形成的。
