1-（2，4，6-三甲基）苯基-3-二环己基膦茚四氟硼酸盐的合成

eprotonation of 1-(2,4,6-trimethyl)phenyl indene by BuLi and trapping of the lithiated intermediate by dicyclohexylphosphine chloride afforded regiospecific 1-[1-(2,4,6-trimethyl)phenyl]indenyl-3- dicyclohexylphosphine as the only product, this phosphine ligand react with tetrafluoroborate acid give the air stable 1-[1-(2,4,6-trimethyl)phenyl]indenyl-3-dicyclohexylphosphoium tetrafluoroborate. The product has been fully characterized by spectroscopy, and X-ray crystal diffraction techniques.
