 Synthesis of 2,3,4,5-(Tetra-4-pyridinyl)cyclopenta-2.4-dien-1-one toward Tricarbonyl-(η5-(penta-4-pyridyl)cyclopentadienyl)chromium-(I)

[4]Metallocenophanes are interesting because of their ability to be utilized as a synthetic reagent, such as a catalytic compound. In order to study them and their synthetic functionality, a synthesis of 1,4-bis-(1,3-cylopentadienyl)butane (the ligand precursor) was proposed from a substitution pathway utilizing a dimesylate derivatives of 1,4-butanediol, deprotonated, and then reacted with ferrous chloride to form [4]ferrocenophane. The synthesis of the precursor ligand had mixed results due to solubility issues, and was eventually changed from using the dimesylate to using 1,4-dibromobutane. This was more efficient, however the deprotonation step was also difficult and was not resolved until much later after the project was passed to another student. The synthesis of [4]ferrocenophane has not yet been achieved.
