The syntheses of some triphenylphosphinalkylimines and their addition reactions with alkyl halides to yield mono-and dialkylaminotriphenylphosphonium halides are reported. The limitation of alkyl halide addition reactions has been described. Sterically hindered t- butylmethylamine and f-butylethylamine have been prepared through the hydrolysis of the corresponding dialkylaminotriphenylphosphonium halides.
