The radical cation [Fe(CO)3(PPh3)2]+: novel source of iron(II) carbonyl complexes
Abstract
The iron(I) complex [Fe(CO)3(PPh3)2]+ undergoes novel radical–radical coupling and redox reactions, with paramagnetic (NO, NO2, etc.) and diamagnetic ([S2CNR2]– S2[graphic omitted]R3, etc.) ligands, respectively, to give iron(II) carbonyl derivatives such as [Fe(NO2)(CO)3(PPh3)2]+ and [Fe(CO)2(PPh3)2(S2CPPh3)]2+.
