Reaction of Perrhenate with Phthalocyanine Derivatives in the Presence of Reducing Agents and Rhenium Oxide Nanoparticles in Biomedical Applications.

ABSTRACT: A novel alternative route to access rhenium(V)-phthalocyanine complexes through direct metalation of metal-free phthalocyanines (H₂ Pcs) with a rhenium(VII) salt in the presence of various two-electron reducing agents is presented. Direct ion metalation of tetraamino- or tetranitrophthalocyanine with perrhenate (ReO₄^- ) in the presence of triphenylphosphine led to oxidative decomposition of the H₂ Pcs, giving their respective phthalonitriles. Conversely, treatment of H₂ Pcs with ReO₄^- employing sodium metabisulfite yielded the desired Re^V O-Pc complex. Finally, reaction of H₂ Pcs with ReO₄^- and NaBH₄ as reducing agent led to the formation of rhenium oxide (Re<
