An alternative synthesis has been developed with the objective of extending the applications of bipyrenol in mind. The key reaction involves the oxidative coupling of 2-hydroxypyrene menthyl carbonate to afford the corresponding pyrene dimer. In marked contrast to our previous method, i.e., the oxidation of 2-hydroxypyrene, the revised method is a clean and high-yielding reaction. By optimizing the reaction conditions, the yield of the alternative synthesis is increased to 88%.
