Increasing the TEMPO! Transition metals are not necessary for oxidative polymerization of 2,7-di-magnesated fluorenes. Oxidation readily occurs by using the commercially available 2,2,6,6-tetramethyl-piperine 1-oxyl radical (TEMPO) as an oxidant. Polyfluorenes with Mn of up to 9000 g mol−1 can be obtained (see scheme).
