Abstract: Synthesis of 3-[1-(2,4,6-trimethyl)phenyl]indenyl-dicyclohexylphosphoium tetrafluoroborate deprotonation of 1-(2,4,6-trimethyl)phenyl indene by BuLi and trapping of the lithiated intermediate by Cy2PCl afforded regiospecific 3-[1-(2,4,6-trimethyl)phenyl]indenyl-dicyclohexylphosphine as the product, this phosphineligand react with tetrafluoroborate acid give the air stable 3-[1-(2,4,6-trimethyl)phenyl]indenyl-dicyclohexylphosphoium tetrafluoroborate. The product has been fully characterized by 1H NMR, 13C NMR 31P NMR spectroscopy, and X-ray crystal diffraction techniques.
