The FeIII(phen)3 catalysis of the benzylic C(sp3)–H azidation of indoles has been investigated. The Fe(III) complex can selectively oxidize indoles to form arene radical cations, which are transformed into benzylic C(sp3) radical intermediates. This strategy exhibits a difference in reactivity between N-heteroarenes and benzene, which is difficult to achieve via direct hydrogen abstraction approaches
已经研究了吲哚的苄基 C(sp 3 )–H 叠化的Fe III (phen) 3催化。Fe(III) 络合物可以选择性地氧化吲哚形成芳烃自由基阳离子,这些阳离子被转化为苄基 C(sp 3 ) 自由基中间体。该策略表现出N-杂芳烃和苯之间的反应性差异,这很难通过直接夺氢方法实现。构建了各种生物相关的叠氮化物前体,突出了这种温和的第一行过渡金属催化剂系统的实用性。
