Unusual reactions of [{μ-(phthalazine-N2:N3)}Fe2(μ-CO)(CO)6] with organolithium reagents. A novel coordination mode of 1,2-diazane diiron carbonyl compounds

Abstract

[{μ-(Phthalazine-N2:N3)}Fe2(μ-CO)(CO)6] (1) 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[double bond, length as m-dash]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 [(μ-{1-(p-CH3C6H4)-phthalazine-N2:N3})Fe2(μ-CO)(CO)6] (8) and [(μ-{1-(p-CH3OC6H4)-phthalazine-N2:N3})Fe2(μ-CO)(CO)6] (9), respectively. The structures of complexes 4 and 9 have been established by X-ray diffraction studies.
