We show that a widely used conducting polymer, poly(3,4-ethylene dioxythiophene) (PEDOT), reacts with benzylic alcohols upon heating under an inert atmosphere to give the corresponding homoether and water without the need to attach a secondary reagent or other reactive unit. This reaction does not appear to result from endogenous acid or from a buildup of acid on the polymer. Apart from the water byproduct, small amounts of aldehyde are also produced during this process. Far from being chemically inert, PEDOT facilitates facile reactions with benzylic alcohols. Because alcohols are common additives to conducting polymers, this reaction may be detrimental to the long-term stability of devices using PEDOT.
