Electrochemical Investigation of Iron-Catalyzed Atom Transfer Radical Polymerization.

ABSTRACT: Use of iron-based catalysts in atom transfer radical polymerization (ATRP) is very interesting because of the abundance of the metal and its biocompatibility. Although the mechanism of action is not well understood yet, iron halide salts are usually used as catalysts, often in the presence of nitrogen or phosphorous ligands (L). In this study, electrochemically mediated ATRP (eATRP) of methyl methacrylate (MMA) catalyzed by FeCl₃, both in the absence and presence of additional ligands, was investigated in dimethylformamide. The electrochemical behavior of FeCl₃ and FeCl₃/L was deeply investigated showing the speciation of Fe(III) and Fe(II) and the role played by added ligands. It is shown that amine ligands form stable iron complexes, whereas phosph
