英文摘要: The reactions of diiron cationic carbyne complexes [Fe^2(μ-CO)(μ-Car)(CO)^2{(η~5-C^5H^4)^2Si-(CH^3)^2}]RRr^4 (4,Ar=C^6h^5; 5, Ar=PCH^3C^6H^4; 6,Ar=p-CF^3C^6H^4) with NaSR(R=CH^3C^6H^5, p-CH^3C^6H^4 in THF at low temperature afford diiron bridging mercaptocarbene complexes [Fe2(μ-CO){μ-C(SR)Ar}(CO)^2{(η~5-C^5H^4)^2Si(CH^3)^2}; (9, Ar=C^6H^5, R=CH^3; 10,Ar=C^6H^5, R=C^6H^5; 11,Ar=C^6H^5,R=p-CH^3C^6H^4; 12,Ar=P-CH^3C^6H^4,R=CH^3; 13, Ar=p-CH^3C^6H^4,R=C^6H^5;14,Ar=P-CH^3C^6H^4,R=P-CH^3C^6H^4;15,Ar=P-CF^3C^6H^4,R=CH^3; 16, Ar=P-CF^3C^6H^4,R=C^6H^5; 17,Ar=P-CF^3C^6H^4,R=p-CH^3C^6H^4). Compound 6 reacts with [(μ-Sli)(μ-SC^6H^5)Fe^2(CO)^6] to give the novel iron-sulfur cluser bridging carbene complex [Fe^2(μ-CO)(μ-CC^6H^45CF^3-p)(CO)^2{η^5-C^5H^4)^2Si(CH^3)^2}(μ-S)(μ-SC^6H^5)Fe^2(CO)^6](18). Analogous iron-sulfur cluster bridging carbene complexes [Fe^2(μ-CO)(μ-Car)(CO)^2(η^5-C^5H^5)^2-(μ-S)(μ-SC^6H^5)Fe(CO)^6] (19,Ar=C^6H^5; 20,Ar=p-CH^3C^6H^4)can also be obtained by the reactions of diiron cationic carbyne complexes [Fe^2(μ-CO)(μ-CO)(μ-Car)(CO)^2(η~5C^5H^5)^2]BBr^4(7,Ar=C^6H^5;8,Ar=p-CH^3C^6H^4)with [(μ-Sli)(μ-SC^6H^5Fe^2(CO)^6]. The structures of complexes 9, 13, 16, and 18 have been established by X-ray crystallography.
