Abstract—A method was developed for the synthesis of three rhenium complexes, (5,10,15,20-tetraphenyl-
21H,23H-porphinato)(phenoxo)rhenium(III) (PhO)ReTPP, (5,10,15,20-tetraphenyl-21H,23H-porphi-
nato)(chloro)rhenium(III) (Cl)ReTPP, and -oxo-bis[(oxo)-(5,10,15,20-tetraphenyl-21H,23H-porphinato)rhe-
nium(V)] [O=ReTPP]₂O, by one reaction between porphyrin H₂TPP and H₂ReCl₆ in boiling phenol. In the
complex formation reaction accompanied by the redox process, only the metal cation is involved in the trans-
formation. Rhenium(IV) as chlororhenic acid dispropoportionates without participation of solvent or porphyrin
to give Re(III) and Re(V) complexes. The chemical structures of the products were established by spectral and
elemental analysis. Characteristics of the UV, Vis, IR, and ¹H NMR spectra, the chromatographic mobility, and
stability of the complexes were determined.
