文摘

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