The unprecedented nucleophilic addition of 2,4,6-triphenylpyrylium salt to η3-phosphine PR3 (R=Me, Et, Ph) afforded novel trisubustituted (1,3,5-triphenyl-4-trisubstituted phosphoranylidene-5-one) phosphonium perchlorates (1) in good yields. All products were fully characterized by 1H NMR, 13C NMR, 31P NMR, MS techniques and elemental analyses.

Key words: η3-phosphine, conjugated addition, pyrylium salt, phosphonium salt
