The ruthenium(0) dinitrogen complexes [Ru(N)(PP)] [PP = P(CHCHPR); R = Pr or Cy] react with triflic acid and other strong acids to afford mixtures of ammonia and hydrazine. In this reaction, Ru(0) is oxidized to Ru(II), and depending on the solvent, Ru(II) benzene or triflate complexes are isolated and characterized from the reactions with triflic acid as the final metal-containing products from the reaction. The Ru(II) products are isolated and reduced back to Ru(0) dinitrogen complexes providing a cycle for the reduction of coordinated dinitrogen.
钌(0)二氮配合物[Ru(N)(PP)] [PP = P(CHCHPR)；R = Pr 或 Cy]与三氟乙酸和其他强酸反应，生成氨和联氨的混合物。在这个反应中，Ru(0)被氧化为 Ru(II)，根据溶剂的不同，Ru(II)苯或三氟甲磺酸根配合物从与三氟乙酸的反应中被分离出来并得到表征，作为反应的最终含金属产物。Ru(II)产物被分离出来并还原回 Ru(0)二氮配合物，为配位二氮的还原提供了一个循环。
