U. Siemeling, [MEO(CH2CH2O)(3)(CH2)(3)C(5)ME(4)]FECL - A HALFSANDWICH IRON(II) CHLORIDE COMPLEX OF REMARKABLE STABILITY, Chemische Berichte, 128(11), 1995, pp. 1135-1136
Reaction of iron(II) chloride with one equivalent of [MeO-(CH2CH2O)(3)
(CH2)(3)C(5)Me]Li in THF yields the title halfsandwich complex 1, whic
h is stable in solution up to room temperature. Compound 1 reacts with
C5H5Li and CO to give [MeO(CH2CH2O)(3)(CH2)(3)C(5)Me(4)]Fe(C5H5) (2)
and [MeO-(CH2CH2O)(3)(CH2)(3)C(5)Me(4)]Fe(CO)(2)Cl (3), respectively i
n high yields.
