Synthetic Route of 1271-48-3, Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. In a document type is Article, and a compound is mentioned, 1271-48-3, name is 1,1′-Ferrocenedicarboxaldehyde, introducing its new discovery.
The synthesis and characterization of the new ligand 4′-ferrocenylterpyridine is reported together with the synthesis and characterization of a new C3-ferrocenophane containing three acetylpyridine units. The terpyridine ligand was prepared in a two-step synthesis from ferrocenecarbaldehyde by aldol condensation and subsequent cyclization. Attempts to prepare the analogous 1,1′-bis-terpyridylferrocene derivative resulted in the formation of a new ferrocenophane: a consequence of inter-annular attackof an anion generated on the side chain of one cyclopentadienyl ring on a carbonyl centre on the side chain of the other cyclopentadienyl ring. The single crystal X-ray structure of this ferrocenophane, [(eta-C5H4 CHCH2C(O)2-C5H4N)2CHC(O)2-C5H4N]Fe, as its dichloromethane solvate, [Fe(C33H27N3O3)].CH2Cl2, has been determined.
