ted complexes (μ-k2N,C-PhN COCH2Ph)Fe2(CO)5(L)(μ-SCH3) (6, L = PPh3; 8, L = PPh2Py) besides an unexpected monophosphine-disubstituted complex (μ-k2N,C-PhN COCH2Ph)Fe2(CO)4(PPh3)2(μ-SCH3) (7). All the new complexes have been characterized by elemental analyses, IR, 1H NMR, 13C NMR and 31P NMR spectroscopy and 1, 2 and 4–8 structurally determined by X-ray crystallography.

摘要在0°C的条件下,PhNHC(S)OR,Et3N和Fe3(CO)12在THF中的三组分反应提供了[(μ-PhNCOR)Fe2(CO)6(μ- S)]-团簇阴离子(R = CH3,CH2Ph)。以S为中心的簇阴离子与CH3I反应生成(μ-k2N,C-PhN COR)Fe2(CO)6(μ-SCH3)(1,R = CH3; 3,R = CH2Ph)和(μ-k2N, C-PhN COCH3)Fe2(CO)6(μ4-S)Fe2(CO)6(μ-SCH3)(2)。在Me3NO存在下1与1当量的PPh2R的进一步反应导致相应的单膦取代的配合物(μ-k2N,C-PhN COCH3)Fe2(CO)5(L)(μ-SCH3)(4,L = PPh3; 5,L = PPh2Py)。类似地,3与PPh2R的反应产生相应的单膦取代的配合物(μ-k2N,C-PhN COCH2Ph)Fe2(CO)5(L)(μ-SCH3)(6,L
