title: Activation of [(99(m))TcO4](-) by phosphonium cations.
abstract: Phosphonium salts in solution or bound to solid phase supports interact with the robust [(99(m))TcO4](-) anion in neutral water. This activated form of [(99(m))TcO4](-) represents a source for complexes with the fac-{(99m)Tc(VII)O3}(+) core, which can be synthesized in high yields and purity.
