4)-trithiolane-5′,2′-tricyclo[3.3.1.1]decane} (1e) with nonacarbonyldiiron (2) have been investigated. The sulfurdithiolatodiiron complexes 3a–e, which can be considered as novel model complexes of the active site of the [Fe-only] hydrogenase, were isolated as the main products of these reactions. X-ray structure analyses were performed on compounds 3b–e. The carbon dithiolato (SCR2S)-bridged diiron side-products
1,2,4-trithiolane (1a), 3,3,5,5-tetramethyl-1,2,4-trithiolane (1b), 3,3,5,5-tetraethyl-1,2,4 的反应-trithiolane (1c), 3,3,5,5-bis(pentaethylene)-1,2,4-trithiolane (1d) 和 di-spirotricyclo[3.3.1.1]decane-2,3″-(1, 2,4)-trithiolane-5',2'-tricyclo[3.3.1.1]decane} (1e) 与 nonacarbonyldiiron (2) 已被研究。硫二硫基二铁配合物 3a-e 可以被认为是 [Fe-only] 氢化酶活性位点的新型模型配合物,作为这些反应的主要产物被分离出来。对化合物 3b-e 进行 X 射线结构分析。还获得了二硫代碳(SCR2S)桥接的二铁副产物
