Clusterverbindungen In der Zuschrift auf S. 15926 berichten Kazuyuki Tatsumi et al. über die Synthese eines Nitrogenase‐PN‐Clustermodells mit Fe8S7(μ‐Sthiolate)2]‐Kern aus dem Cuban‐Synthon Fe4S4(Sthiolat)4].
Constructing synthetic models of the nitrogenase PN‐cluster has been a long‐standing synthetic challenge. Here, we report an optimal nitrogenase PN‐cluster model [{(TbtS)(OEt2)Fe4S3}2(μ‐STbt)2(μ6‐S)] (2) [Tbt=2,4,6‐tris{bis(trimethylsilyl)methyl}phenyl] that is the closest synthetic mimic constructed to date. Of note is that two thiolate ligands and one hexacoordinated sulfide are connecting the two...
