摘要
The compounds Fe-2(CO)(6){C2Et2C[CH2N(Me)CH2Ph]CH} (3) and Fe-3(CO)(8){C2Et2C(H)C-[CH2N(Me)CH2Ph]} (4) resulted from the reaction of Fe-3(CO)(9)(mu(3)-eta(2)-perpendicular to-C2Et2) (1) with the substituted propargylamine N-benzyl-M-methylpropargylamine. Complexes 3 and 4 were characterized by X-ray structural determinations. Complexes 3 and 4 represent two orientations of insertion of the propargylamine between iron and the alkyne ligand of 1. The characteristic feature in both structures is the presence of a ferracyclopentadiene ring. (C) 1998 Elsevier Science S.A. All rights reserved.
