摘要：

A series of new multi-ferrocenyl substituted pyridine derivatives, 4,6-diferrocenyl-3,5-diferrocenylethynyl-2-methylpyridine (1), 3,6-diferrocenyl-4,5-diferrocenylethynyl-2-phenylpyridine (2),4,6-diferrocenyl-3,5-diferrocenylethynyl-2-phenylpyridine (3), 3,5-diferrocenyl-4,6-diferrocenylethynyl-2-phenylpyridine (4) were synthesized by dicarbonylcyclopentadienylcobalt mediated [2 + 2 + 2] cycloaddition reaction. The molecular composition and structure of compounds 1-4 were characterized by FT-IR, NMR, MS, CV and Elemental analysis. The molecular and crystal structure of compound 1 was determined by X-ray single crystal diffraction analysis. The cyclic voltammetry and square wave voltammetry highlight the electrochemical behaviors of compounds 1-4, which indicates multi-step reversible redox processes of ferrocenyl moieties have occurred. The wave splitting and Delta E-1/2 (oxidation potential difference) values of 1-4 were carefully analyzed, which reveals that the interactions between the ferrocenyl units of 1-4 are related to their molecular structures. The molecular structures of isomers 2-4 have been identified by their electrochemical properties and spectroscopic information. (C) 2014 Elsevier Ltd. All rights reserved.
