Iron complexes containing hydrazido(1-) and diazene ligands were investigated as potential intermediates in the reduction of N(2) to NH(3). Generation of cis-Fe(DMeOPrPE)(2)(eta(2)-N(2)H(3)) and cis-Fe(DMeOPrPE)(2)(eta(2)-N(2)H(2)) (DMeOPrPE = 1,2-bis(dimethoxypropylphosphino)ethane) was achieved by addition of base to cis-Fe(DMeOPrPE)(2)(N(2)H(4)). The hydrazine, hydrazido(1-), and diazene complexes can be interconverted by protonation/deprotonation reactions.
含肼基(1-)和二氮烯配体的铁配合物作为将N₂还原为NH₃的潜在中间体进行了研究。通过向顺式-[Fe(DMeOPrPE)₂(N₂H₄)]²⁺中加入碱,生成了顺式-[Fe(DMeOPrPE)₂(η²-N₂H₃)]⁺和顺式-Fe(DMeOPrPE)₂(η²-N₂H₂)(DMeOPrPE = 1,2-双(二甲氧基丙基膦基)乙烷)。肼、肼基(1-)和二氮烯配合物可通过质子化/去质子化反应相互转化。
