摘要:
A series of complexes of the type trans-W[PtCl2(eta(2)-ethene)(N-ferrocenyl methyl)amine)] complexes, N-ferrocenylmethylamine = [(eta(5)-C-5-H-5)Fe(eta(5)-C-5-H4CH2NHR], R = (Me, Pr-i, Bu-s, Bu-t, CH2Ph, (p-OCH3)Ph, (o-(OCH3)Ph, (p-CH3)Ph, (o-CH3)Ph, (m-CH3)Ph, (p-Cl)Ph) have been synthesized and characterized on the basis of elemental analysis, IR, H-1 and C-13 NMR spectroscopic methods. The CpCH2NHR (Cp = (eta(5) -C5H5)Fe(eta(5)-C5H4), region of the H-1 NMR spectrum of the complexes has been investigated and shown to contain inequivalent methylene protons, NH-CH and Pt-195 -N-CH coupling take place.
