Both poly(3,4-ethylenedioxythiophene) and poly(pyrrole) mediate a pinacol rearrangement of 1,2-diols to give ketones or aldehydes in comparable yields to those observed for treatment with mineral or Lewis acids. The two-phase reaction medium in hydrocarbon solvents allows facile recovery of the products. Both the polymer and the hydrocarbon solvent may be reused.
