Substitution Polymerization of Chloroarene Complexes

Polymers 15a and 15b were isolated as light yellow precipitates in 92 and 93% yields, respectively. These cyclopentadienyliron-coordinated polymers exhibited good 

These polymerization reactions were carried out in a number of different solvents depending on the solubility of the starting polymer. Ideally, acetone was used however, most of the polymers were not completely soluble in acetone. Acetonitrile was also used however, attempts were also made with DMF and DMSO. The
