The cluster anion [Fe3(CO)9(μ3-S-t-C4H9)]−, which is easily obtained by deprotonation from the cluster compound Fe3(CO)9(μ2-H)(μ3-S-t-C4H9), reacts with XCl2 by elimination of t-C4H9Cl and Cl− to give the clusters Fe3(CO)9(μ3-S)(μ3-X) (X = PR: I, X = AsR: II, X = SO: III), in which one edge of the iron triangle is opened. The μ3-PR-bridged clusters I can also be obtained by reactions of SCl2 with the
簇阴离子的[Fe 3(CO)9(μ 3 -STC 4 ħ 9)] - ,其容易被去质子化从簇化合物的Fe得到3(CO)9(μ 2 -H)(μ 3 -STC 4 ħ 9)中,用XCL发生反应2通过消去的TC 4 ħ 9 Cl和氯- ,得到簇的Fe 3(CO)9(μ 3 -S)(μ 3-X)(X = PR:I,X = AsR:II,X = SO:III),其中铁三角的一个边打开。该μ 3 -PR桥接我还可以通过在SCL的反应获得簇2与阴离子的[Fe 3(CO)9(μ 3 -PR)] 2-,选自Fe制备3(CO)9(μ 2 - 1H)2(μ 3 -PR)通过去质子化。I和II的几何结构以X射线结构分析为例。讨论了针对I的高产率合成提出的反应途径的实验证据。
