Starting from nitroarenes, under hydrosilylation conditions, using a well-defined N-heterocyclic carbene iron(0) catalyst, (IMes)Fe(CO)4, the corresponding aniline derivatives were produced in 61–92% isolated yields. More impressively, a selective synthesis of cyclic amines such as pyrrolidines, piperidines and azepanes were conducted from levulinic acid, 1,5- and 1,6-keto acids, respectively. The
从硝基芳烃开始,在氢化硅烷化条件下,使用明确定义的N-杂环卡宾铁 (0) 催化剂 (IMes)Fe(CO) 4,以 61-92% 的分离产率生产相应的苯胺衍生物。更令人印象深刻的是,分别从乙酰丙酸、1,5- 和 1,6- 酮酸选择性合成了环胺,如吡咯烷、哌啶和氮杂。连续程序在可见光照射和热条件下进行,有 20 个实例,分离产率高达 69%。
