Synthesis and structure of bis- and tris-ferrocene containing N-methylimide foldamers

摘要: Abstract The synthesis and conformational analysis of dimer Fc–CO–NMe–CO–Fc (5) trimer Fc–CO–NMe–CO–Fn–CO–NMe–CO–Fc (6) have been described. It has shown by means spectroscopic studies, X-ray crystallography, molecular modeling, that these molecules are dominated cis–cis conformation. Furthermore, we recognized for the first time, such type organometallics possess elements chiral helicity. Their crystal lattices characterized π–π CH–π intermolecular interactions CH⋯O C hydrogen bonds (6). We believe foldamers 5/6 stabilized special aromatic between closer cyclopentadienyl rings juxtaposed ferrocene units.
