Some Features of Reaction of 2-Methyl-1,4-naphthoquinone with H-Phosphonium Salts Based on Diphenylphosphine

Аннотация

It was shown that the direction of the reaction of 2-methyl-1,4-naphthoquinone with H-phosphonium salts obtained from diphenylphosphine and trifluoromethanesulfonic or trifluoroacetic acids depends on the nature of the anion. Structure of the obtained mono- and diphosphinates, as well as the quasi-phosphonium salt, was established by NMR spectroscopy and single crystal X-ray diffraction methods.
