An improved strategy for the synthesis of 3,30-(oxy-p-phenylene)bis(2,4,5-triphenylcyclopentadienone) was developed, which
includes three steps: Friedel–Crafts reaction, oxidation and condensation. Importantly, the use of KMnO4 made the second step
simple and efficient, which has potential application to synthesis of bis(cyclopentadienone)s. The course of oxidation has been
confirmed by isolated intermediates.
