Synthesis, structural characterization and electrochemical study of 1,1′-ferrocenylene labeled amino acids
摘要:
Unsymmetrical 1,1'-disubstituted ferrocenes bearing an amino acid moiety and a conjugated electron density controlling substituent were synthesized conveniently starting from 1,1'-ferrocenedicarbaldehyde. The novel ferrocene amino acid derivatives were completely characterized from their MS, H-1 NMR and C-13 NMR spectra. Their electrochemical behavior was studied by cyclic voltammetry. Their formal redox potentials E-f were slightly influenced by the nature of the amino acid and mainly by the kind of the ethenyl substituent. Furthermore all the (Z)-isomers exhibited a slight anodic shift compared with the corresponding (E)-isomers. (c) 2006 Elsevier B.V. All rights reserved.
