SYNTHESIS OF IRON(II) PHOSPHITE COMPLEXES

The cationic iron(II) complexes, [Fe(P(OR)3)5X]+, have been prepared by reactions involvin oxidation of Fe(P(OR)3)5 (for X = H, Me, CF3) or addition of phosphites to iron bis(tetrahydrofuran) dihalide complexes (for X = Cl, Br, I). This latter reaction proceeds, under different conditions, through two distinctly different isolable species, both of which have been characterized by spectroscopic techniques including simulation of the 31P{1H} NMR spectra. © 1979.
