A novel approach has been proposed to the synthesis of phosphonium salts containing a 1,4-dihydroxybenzo fragment via reaction of 2-methyl-1,4-benzoquinone or 2-isopropyl-5-methyl-1,4-benzoquinone with PH-phosphonium salts generated in situ from triphenylphosphine and trifluoromethanesulfonic or trifluoroacetic acid. The structure of the synthesized phosphonium salts was determined by NMR spectroscopy and X-ray analysis.

The reaction of the R-pulegone with P–H-phosphonium salts gives the corresponding 8-phosphonio-p-menthan-3-one salts with high regio- and stereoselectivity. The structure of salts was determined by NMR and IR spectroscopy, mass spectrometry and X-ray diffraction analysis.
