双 Grignard 试剂 BrMg(CH_2)_4MgBr 可还原断裂两分子μ-S_2Fe_2(CO)_6的硫—硫键,生成丁撑桥联双簇铁硫中间物 A,[(μ-BrMgS)Fe_2(CO)_6]μ—S(CH_2)_4S—μ[(μ-BrMgS)Fe_2(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)Fe_2(CO)_6]μ—S(CH_2)_4S—μ[(μ-ZS)Fe_2(CO)_6].除通过 IR、~1HNMR 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.
The double Grignard reagent BrMg (CH_2) _4MgBr can reduce the sulfur-sulfur bond of two molecules of μ-S_2Fe_2 (CO) _6 to form the bridged double cluster iron-sulfur intermediate A, [(μ-BrMgS) Fe_2 (CO) (μ-BrMgS) Fe_2 (CO) _6], A is further substituted with a halogenated hydrocarbon, chloromethyl ether, a chlorinated ketone, a chlorinated ester or an acid chloride in situ , A total of ten novel dibasic bridged double-group iron-sulfur complexes B were obtained, and the results showed that there were 10 new structures of [μ-ZS] Fe_2 (CO) _6] μ-S (CH_2) _4S-μ [ CO) _6]. In addition to the IR, ~ 1HNMR and hydrocarbon analysis confirmed the structure of the above complexes and deduced the possible conformation of certain complexes, but also by X-ray diffraction confirmed that the structure of one of the complexes B (1) And conformation.
