Session: Organometallic Chemistry: Synthesis and Characterization - Early Transition Metals:

Our goal was to adopt a lab-based on previously established syntheses for the Geodken’s macrocycle in order to accomplish synthesizing a nickel macrocycle accurately and then remove the nickel to isolate the macrocycle. Geodken’s Macrocycle synthesis has been done before using a nickel template before being isolated. After isolation, we can add metals to the center of the macrocycle. In our project, we will be adding other metals to the synthesis, such as +2 metals after isolation of the macrocycle. These +2 metals can be iron, chromium, or copper, which have not been used by Geodken’s Macrocycle previously. We will use 1H NMR and IR to determine if these metals have been introduced into the macrocycle. Similarly, crystallization and structure determination with single-crystal x-ray diffraction can conclusively determine if the desired metal macrocycle was synthesized.
