双Grignard试剂BrMg(CH2)4MgBr可还原断裂两分子μ-S2Fe2(CO)6的硫-硫键,生成丁撑桥联双簇铁硫中间物A, [(μ-BrMgS)Fe2(CO)6]μ-S(CH2)4S-μ-[(μ-BrMgS)Fe2(CO)6], A于原位(in situ)进一步同卤代烃、氯甲醚、氯代酮、氯代酯或酰氯作用, 共得到10个结构新颖的丁撑桥联双簇铁硫配合物B, [(μ-ZS(Fe2(CO)6]μ-S(CH2)4S-μ[(μ-ZS)Fe2(CO)6]. 除通过IR、^1H NMR及碳氢分析证实上述配合物的结构和推得某些配合物可能的构象外, 还用X衍射法确证了其中一个配合物B(1)的结构和构象.

BrMg(CH2)4MgBr reductively cleaved the S-S bond of 2 mols. of m-S2Fe2(CO)6 to give [(m-BrMgS)Fe2(CO)6]-(m-S(CH2)4S)-[(m-BrMgS)Fe2(CO)6] (I), which contains a bridging butylene group and 2 Fe2S2 cluster cores. Reactions of I with alkyl halides, chromomethyl Me ether, chloroketones, chloroesters or acyl chlorides in situ give 10 [(m-RS)Fe2(CO)6]-m-(S(CH2)4S)[(m-RS)Fe2(CO)6] (II). For all II structures were established by IR, 1H NMR and C, H anal. while conformers of some complexes were deduced from 1H NMR data.
