transfer from a catalytically generated cobalt(III)-hydride complex to the olefins proceeded regioselectively, and the nucleophilic addition of benzotriazoles occurred selectively at their N2-positions. The synthetic utility of the obtained N2-alkylated benzotriazoles as stable amine protecting groups under various reaction conditions was demonstrated, and the products were also transformed into primary
开发了钴催化的非活化烯烃的马氏化学选择性加氢胺化反应。氢原子从催化生成的氢化钴(III)络合物向烯烃的转移选择性进行,苯并三唑的亲核加成选择性地发生在它们的N2位。证明了所获得的N 2-烷基化的苯并三唑在各种反应条件下作为稳定的胺保护基的合成效用,并且产物还通过锌介导的还原转化为伯胺。
