title: Basicity of some phosphines in THF.
abstract: [reaction: see text] The reaction of several phosphines with an acidic indicator gives both ion pairs and free ions. The value obtained for the pKa of tribenzylphosphine is shown to be reasonable by MO computations. An important limitation is demonstrated for the Fuoss equation of dissociation of ion pairs.
