摘要: A series of low-coordinate, paramagnetic iron complexes in a tris(thioether) ligand environment have been prepared. Reduction ferrous {[PhTttBu]FeCl}2 [1; PhTttBu = phenyltris((tert-butylthio)methyl)borate] with KC8 the presence PR3 (R Me or Et) yields high-spin, monovalent phosphine [PhTttBu]Fe(PR3) (2). These provide entry into other low-valent derivatives via substitution. Carbonylation led to smooth formation low-spin dicarbonyl [PhTttBu]Fe(CO)2 (3). Alternatively, replacement diphenylacetylene produced high-spin alkyne complex [PhTttBu]Fe(PhCCPh) (4). Lastly, 2 equiv adamantyl azide undergoes 3 + cycloaddition at 2, yielding dialkyltetraazadiene 5.
