分子氮络合物是当前小分子络合物化学中发展较快并取得显著成果的领域。目前已经合成一批分子氮络合物在温和条件下能用作高效率、高选择性的催化剂,其中氮分子是与过渡金属络合而活化的。本文综述稳定分子氮,络合物的分类、合成、络合N_2分子的活化途径及利用,进而探讨从分子氮络合物合成新的有机化合物,展望从苯和氮直接合成苯胺以及从空气中的氮和二氧化碳直接合成尿素。
Molecular nitrogen complex is the current rapid development of small molecule complex chemistry and achieved remarkable results in the field. At present, a number of molecular nitrogen complexes have been synthesized which can be used as a highly efficient and highly selective catalyst under mild conditions, in which nitrogen molecules are complexed with transition metals and activated. In this paper, we review the classification of stable molecular nitrogen, the classification of complex, the synthesis and complexation of N_2 molecules, and then explore the synthesis of new organic compounds from molecular nitrogen complexes. The direct synthesis of aniline from benzene and nitrogen, The nitrogen and carbon dioxide directly synthesize urea.
