英文摘要: [{mu-(Pyridazine-N-1: N-2)} Fe-2(mu-CO)(CO)(6)] ( 1) reacts with aryllithium reagents, ArLi (Ar = C6H5, m-CH3C6H4) followed by treatment with Me3SiCl to give the novel pyridazine-coordinated diiron bridging siloxycarbene complexes [(C4H4N2) Fe-2{mu-C(OSiMe3) Ar}(CO)(6)] ( 2, Ar = C6H5; 3, Ar = m- CH3C6H4). Complex 2 reacts with HBF4 center dot Et2O at low temperature to yield a cationic bridging carbyne complex [(C4H4N2) Fe-2(mu-CC6H5)(CO)(6)] BF4 (4). Cationic 4 reacts with NaBH4 in THF at low temperature to afford the diiron bridging arylcarbene complex [(C4H4N2) Fe-2{mu-C(H) C6H5}(CO)(6)] ( 5). Unexpectedly, the reaction of 4 with NaSCH3 under similar conditions gave the bridging arylcarbene complex 5 and a carbonyl-coordinated diiron bridging carbene complex [Fe-2{mu-C(SCH3) C6H5}(CO)(7)] ( 6), while the reaction of NaSC6H4CH3-p with 4 affords the expected bridging arylthiocarbene complex [(C4H4N2) Fe-2{mu-C(SC6H4CH3-p) C6H5}(CO)(6)] ( 7), which can be converted into a novel diiron bridging carbyne complex with a thiolato-bridged ligand, [Fe-2(mu-CC6H5)(mu-SC6H4CH3-p)(CO)(6)] ( 8). Cationic 4 can also react with the carbonylmetal anionic compound Na-2[Fe(CO)(4)] to yield complex 5, while the reactions of 4 with carbonylmetal anionic compounds Na[M(CO)(5)(CN)] (M = Cr, Mo, W) produce the diiron bridging aryl( pentacarbonylcyanometal) carbene complexes [(C4H4N2) Fe-2-{mu-C(C6H5) NCM(CO)(5)}(CO)(6)] ( 9, M = Cr; 10, M = Mo; 11, M = W). The structures of complexes 2, 5, 6, 8, and 9 have been established by X-ray diffraction studies.
