英文摘要	The reactions of he dimethylsilane-bridged cationic carbyne complexes of diiron, [Fe^2(μ-Car)(CO)^2 [η~5-C^5H^4Si(CH^3)^2}BBr^4(1,Ar=C^6H^5; 2, Ar=Pcf^3H^4), with carbonylmetal anionic compounds Na[M(CO)^5CN](4,M=Cr;5, M=Mo; 6, M=W) in THF at low temperature afford diiron bridging carbene complexes [Fe^2(μ-(CO)){μ-C(Ar)NCM(CO)^5}(CO)^2{(η~5-C^5H^4)^2Si(CH^3)^2}](9, M=Cr, Ar=C^6H^5; 10, M =Mo, Ar=C^6H^5; ; 11, M=W,Ar=C^6H^5; 12, M=Cr, Ar=p-CF^3C^6H^4; 13, M=Mo, Ar=p-CF^3C^6H^4; 14, M=W, Ar=p-CF^3C^6H^4). In contrast to the reaction of 1 and 2 cationic carbyne complex [Fe^2(μ-CO)(μ-CC^6H4CH^3-p)(CO)^2{(η~5-C^5H^4)^2Si(CH^3)^2}]BBr^4(3) reacts with 4-6 under the same conditions to produce novel cationic bridging carbyne complexes [Fe^2(μ-CO)(μ-CC^6H4CH^3-p)(CO)^2{(η~5-C^5H^4)^2Si(CH^3)^2}]+[M(CO)^5CN]-(15,M=CR; 16,M=MO; 17,M=W). Analogous cationic bridging carbyne complex [[Fe^2(μ-CO)(μ-CC^6H4CH^3-p)(CO)^2{(η~5-C^5H^4)^2Si(CH^3)^2}+[Fe(CO)^4CN]-(18) can also be obtained from the reaction of 3 with Na[Fe(CO)^4CN] (7). Complex 15 or 16 reacts with NaSR (R=CH^3, C^6H^5, p-CH^3C^6H^4) to give bridging mercaptocarbene complexes [Fe^2(μ-CO){μ-C(SR)C^6H^4CH^3-p} (CO)^2{η~5-C^5H^4)^2Si(CH^3)^3}] (19, R=CH^3; 20, R=C^6H^5; 21, R=p-CH^3C^6H^4) in high yields. The related reaction of 1 with NaN(SiMe^3)^2 affords a novel benzonitrile-coordinated diiron complex [[Fe^2(μ-CO^2(CO)NCC^6H^5{η~5-C^5H^4)^2Si(CH^3)^2}] (22). Unexpectedly, the reactions of 1 and 2 with 7 yield diiron bridging arylcarbene comlexes [Fe^2(μ-CO){μC(H)Ar}(CO)^2{(η~5-C^5H^4)^2Si(CH^3)^2}](23, Ar=C^6H^5; 24, Ar=p-CF^3C^6^H^4). The products 23 and 24 and bridging p-tolyl-carbene complex [Fe^2(μ-CO){μ-(CO){μ-C(H)C^6H^4CH^3-p}(CO)^2{η~5-C^5H^4)^2Si(CH^3)^2}] (2) were also obtained from the reactions of 1-3 with [PPh^3)^2N][Cr(CO)^4NO] (8). The structures of 14.15,22, and 23 have been established by X-ray crystallography.
