An Alternative Synthesis of Bipyrenol: A High-Yield Oxidative Coupling Reaction of a Pyrene Derivative with Cu(BF₄)₂·nH₂O

Abstract

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%.

Key words

BINOL - bipyrenol - copper(II) tetrafluoroborate - oxidative coupling - pyrene

• 15 The stoichiometry of this hygroscopic reagent was regarded to be Cu(BF₄)₂·6H₂O as the idealized hexahydrate salt. However, it was too difficult to weigh the reagent accurately because of the high hygroscopicity of commercially available Cu(BF₄)₂·nH₂O.
