{Micro-(phthalazine-N2:N3)}Fe2(micro-CO)(CO)6 reacts with organolithium reagents, RLi (R = CH3, C6H5, p-CH3C6H4, p-CH3OC6H4, p-CF3C6H4, p-C6H5C6H4), followed by treatment with Me3SiCl to give the novel diiron carbonyl complexes with a saturated N-N six-membered diazane ring ligand, [{C6H4CH(R)NNCH2}Fe2(C=O)(CO)6](2, R = CH3; 3, R = C6H5; 4, R =p-CH3C6H4; 5, R =p-CH3OC6H4; 6, R =p-CF3C6H4; 7, R =p-C6H5C6H4). Compounds 4 and 5 were treated with [(NH4)2Ce(NO3)6] to afford the aryl-substituted phthalazine-coordinated diiron carbonyl compounds (micro-{1-(p-CH3C6H4)-phthalazine-N2:N3})Fe2(micro-CO)(CO)6 and (micro-{1-(p-CH3OC6H4)-phthalazine-N2:N3})Fe2(micro-CO)(CO)6, respectively. The structures of complexes 4 and 9 have been established by X-ray diffraction studies.
(邻二氮杂萘 - N2:N3)Fe2(μ - CO)(CO)6 与有机锂试剂RLi（R = CH3、C6H5、p - CH3C6H4、p - CH3OC6H4、p - CF3C6H4、p - C6H5C6H4）反应，随后用Me3SiCl处理，得到具有饱和N - N六元二氮烷环配体的新型二铁羰基配合物[{C6H4CH(R)NNCH2}Fe2(C = O)(CO)6]（2，R = CH3；3，R = C6H5；4，R = p - CH3C6H4；5，R = p - CH3OC6H4；6，R = p - CF3C6H4；7，R = p - C6H5C6H4）。化合物4和5用[(NH4)2Ce(NO3)6]处理，分别得到芳基取代的邻二氮杂萘配位的二铁羰基化合物(μ - {1 - (p - CH3C6H4)-邻二氮杂萘 - N2:N3})Fe2(μ - CO)(CO)6 和(μ - {1 - (p - CH3OC6H4)-邻二氮杂萘 - N2:N3})Fe2(μ - CO)(CO)6。配合物4和9的结构已通过X射线衍射研究确定。
