本文通过(μ-烃硫)(μ-卤化镁硫)六羰基二铁(μ-RS)(μ-XMgS)Fe2(CO)6(A)与反丁烯二酸二乙酯的加成-醇解反应合成了七个新铁硫原子簇络合物, 通式为(μ-RS)[μ-(EtO2C)CH2CH(CO2Et)S]Fe2(CO)6(B). 除用碳氢分析、IR、^1H NMR证实这些产物的结构外, 还通过其羰基取代反应, 合成了四个新双三苯膦衍生物(μ-RS).[μ-(EtO2C)CH2CH(CO2Et)S]Fe2(CO)4(PPh3)2(C), 并对它们的结构和光谱特点进行了初步讨论.

Seven Fe-S cluster complexes, (m-RS)[m-(EtO2C)CH2CH(CO2Et)S]Fe2(CO)6 (R = Me, Et, Pr, Bu, Ph, PhCH2, CH2:CHCH2), were prepared through addition reaction of (m-RS)(m-XMgS)Fe2(CO)6 with diethyl fumarate, followed by alcoholysis of the intermediates formed. The structures of these products were confirmed by elemental anal., IR and 1H NMR spectroscopy. Through CO substitution reaction 4 (m-RS)[m-(EtO2C)CH2CH(CO2Et)S]Fe2(CO)4(PPh3)2 (R = Pr, Bu, Ph, PhCH2) were also prepared and the features of structures and spectroscopy for these derivatives were preliminarily discussed.
