Abstract: The reaction of quinopimaric acid with P–H-phosphonium salts yielded quaternary phosphonium salts containing enol moiety at the phosphorus atom. The reaction proceeded with high regioselectivity. The structures of the resulting compounds were confirmed by NMR and IR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction.

Keywords: phosphonium salts, quinopimaric acid, α,β-unsaturated γ-diketones, quinones, phosphine quaternization, addition reaction.
