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-{99mTcVIIO3}+ core, which can be synthesized in high yields and purity.
