工业上使用铁催化剂生产合成氨的过程需要高温高压和高纯度的氮气和氢气。要想在温和条件下大幅度增产氮肥,必须跳出经典的铁催化剂的框框,致力于发展新型的合成氨催化剂体系。自然界中有多种多样的固氮微生物,它们能在常温常压下摄取大气中的分子氮,并利用生物体内的生物还原剂和水分,将其还原为氨~([1])。因此,生物固氮的化学模拟,是寻找新型的合成氨催化剂的一个重要研究方向。近年来,固氮酶的生物固氮作用以及它的化学模拟,已经取得了一些有意义的初步成果。1964年,Вольпин和Щур~([2])发现一些用于α-烯烃定向聚合的Ziegler型络合催化剂和其相类似的过渡金属有机化合物,能够在温和条件下不可逆地吸收N_2分子, The industrial use of iron catalysts for the production of ammonia requires high temperature, high pressure and high purity nitrogen and hydrogen. In order to produce nitrogen fertilizer under mild conditions, it is necessary to jump out of the classic iron catalyst framework and devote itself to the development of a new type of synthetic ammonia catalyst system. There are a variety of nitrogen-fixing microorganisms in nature that can ingest atmospheric molecular nitrogen at room temperature and atmospheric pressure and reduce it to ammonia ~ ([1]) using biological reducing agents and moisture in the body. Therefore, the chemical simulation of biological nitrogen fixation, is looking for a new type of synthetic ammonia catalyst is an important research direction. In recent years, the biological nitrogen fixation of nitrogenase and its chemical simulation, has made some meaningful preliminary results. In 1964, Вольпин and Щур ~ ([2]) found that some Ziegler-type complex catalysts for the directional polymerization of α-olefins and their similar transition metal organic compounds, which can irreversibly absorb N 2 molecules under mild conditions,
