Calixarenes are macrocyclic oligomers of phenols bridged with methylene groups. They have been studied for applications in host-guest chemistry and some of the metal ion containing calix[4]arene complexes have been found to have promising applications as catalysts. <br/>Our research group is interested in developing synthetic pathways to selectively introduce a transition metal ion. The transition metal ion is selected based on its catalytic properties. So far we have envisioned different synthetic pathways to allow us to attach the transition metal ion. One of these approach uses a calixanion derivative containing alkali ions and subsequent transmetallation. Our group has worked to develop a viable synthetic pathway to form an stable nickel(II) calix[5]arene complex, which was characterized through the use of 1H NMR, FTIR, and efforts are currently underway to complete x-ray crystallography studies. In this presentation we will discuss the synthesis and reactivity of these new Ni(II)-calix[n]arene  (n=4-6) complexes
