Abstract:
An unusual heteroannular cyclization of methyl 4-(((1′- (trimethylsilyl)ethynyl)ferrocenyl)ethynyl)benzoate (11) under the basic desilylation condition yielded 1,1′-(l-methoxy-3-(4′- (methoxycarbonyl)phenyl)-1,3-butadienylene)ferrocene (7), the first reported 1,3-disubstituted 1,3-butadienyl heteroannular bridged [4]ferrocenophane. Compound 7 has been characterized by elemental analysis, IR spectra, 1H NMR spectroscopy and X-ray diffraction analysis. The electrochemical behavior has been investigated by cyclic voltammetry. The DFT calculation results of 7 are also reported. © 2010 Elsevier B.V. All rights reserved.
