Cleavage of cluster iron–sulfide bonds in cyclophane-coordinated FenSm complexes

Résumé

Reaction of the tri(mu-sulfido)triiron(iii) tris(beta-diketiminate) cyclophane complex, Fe3S3LEt/Me (1), or of the di(mu-sulfido)diiron(iii) complex Fe2S2HLEt/Me (5), with the related tri(bromide)triiron(ii) complex Fe3Br3LEt/Me (2) results in electron and ligand redistribution to yield the mixed-ligand multiiron complexes, including Fe3Br2SLEt/Me (3) and Fe2Br2SHLEt/Me (4). The cleavage and redistribution observed in these complexes is reminiscent of necessary Fe-S bond cleavage for substrate activation in nitrogenase enzymes, and provides a new perspective on the lability of Fe-S bonds in FeS clusters.
