Bisphosphonium salt containing a 1,4-dihydroxynaphthyl-substituted moiety was synthesized in high yield by the reaction of 2-methyl-1,4-naphthoquinone with three equivalents of triphenylphosphine and hydrogen bromide. The structure of the synthesized bisphosphonium salt was determined by NMR spectroscopy and X-ray diffraction.
