Abstract

The synthesis and reaction of homoleptic iron(II) complexes with 2,6-di-adamantyl-substituted aryloxides [OC6H2-2,6-Ad-4-R]-([OArAdR]-, Ad = adamantyl, R = Me,iPr) are described. Monomeric two-coordinate iron aryloxides Fe(OArAdR)2(R = Me, 1;iPr, 2) were synthesized by the reaction of Fe[N(SiMe3)2]2with 2 equiv of HOArAdR. Treatment of 1 and 2 with 1-azidoadamantane resulted in intramolecular insertion of an adamantyl nitrene into a methylene C-H bond of the aryloxide adamantyl substituent, yielding the corresponding amine-aryloxide complexes Fe(OArAdR)(OArAdR-NHAd) (R = Me, 3;iPr, 4). Molecular structures of all these complexes are reported. © 2011 Published by Elsevier B.V.
