Abstract

Heating Fe₃(CO)₁₂ with 1,3,5-Me₃C₆(CH₂S₂CNEt₂)₃ (1) in boiling toluene affords [Fe₃(CO)₉(μ₃-S)₂] (2), together with small amounts of the new clusters [Fe₄(CO)₁₂(μ-η¹,κ¹-SCNEt₂)(μ-η¹-CNEt₂)(μ₄-S)] (3) and [Fe₃(CO)₈(η¹-CHNEt₂)(μ₃-S)₂] (4), all three resulting from C-S bond scission. Looking for a more rational route to amino-carbene clusters like 4 we have found that heating Fe₃(CO)₁₂ and thioacetamide in CH₂Cl₂ affords [Fe₃(CO)₈(η¹-CMeNH₂)(µ₃-S)₂] (5). Molecular structures of 3–5 have been determined by single-crystal X-ray diffraction analyses. Cluster 3 contains an edge-bridging amino-carbyne ligand, while 4–5 accommodate Fischer-type amino-carbene ligands.
