Synthesis and structural characterization of 3,5-[1,1′-ferrocenediyl]-1,7-dioxo-1,7-Di(2-pyridyl)-4-(2-pyridylcarbonyl)heptane; an unexpected compound obtained from the reaction of ferrocene-1,1′-dicarbaldehyde with 2-acetylpyridine
摘要:
The reaction of ferrocene-1,1'-dicarbaldehyde with 2-acetylpyridine at room temperature for 24 h results in the synthesis of 3,5-[1,1'-ferrocenediyl]-1,7-dioxo-1,7-di(2-pyridyl)-4-(2-pyridylcarbonyl) heptane instead of the expected enone or 1,5-dicarbonyl. The crystal structure of this compound has been determined by single-crystal X-ray methods. The complex is electroactive and exhibits a reversible iron(II)/(III) process at +0.014 V vs ferrocene.
