“…The oxido‐metallates are already known with porphyrin as macrocyclic systems, [6] and Ziener et al. reported the synthesis of the first oxido rhenium(V)−phthalocyanine complexes [9] . The synthesis involves the reaction of rhenium pentachloride with phthalonitrile to yield the oxido rhenium−phthalocyanine complex and is thus not a direct metalation method.…”

“…This synthesis involves the metalation of a preformed phthalocyanine instead of the one-pot synthesis reported previously. [9] The reaction was carried out in a mixture of n-octanol and water (Scheme 2).…”

“…None of them involve the direction metalation of H 2 Pcs with rhenium metal ions to form rheniumÀ phthalocyanine complexes and very few oxidorhenium(V)À Pc complexes have been isolated. [9] In this paper, we report on our effort to directly synthesise Re V À Pc complexes via the direct metalation of H 2 Pcs, starting from perrhenate in the presence of various reducing agents. To this end, different results were obtained, including the formation of rhenium oxide (Re x O y ) nanoparticles upon reduction of NH 4 ReO 4 with NaBH 4 .…”

“…All the above‐mentioned examples involve the synthesis of rhenium−phthalocyanines through tetracyclization of phthalocyanine precursors with rhenium salts. None of them involve the direction metalation of H 2 Pcs with rhenium metal ions to form rhenium−phthalocyanine complexes and very few oxidorhenium(V)−Pc complexes have been isolated [9] . In this paper, we report on our effort to directly synthesise Re V −Pc complexes via the direct metalation of H 2 Pcs, starting from perrhenate in the presence of various reducing agents.…”

A novel alternative route to access rhenium(V)−phthalocyanine complexes through direct metalation of metal‐free phthalocyanines (H2Pcs) 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 H2Pcs, giving their respective phthalonitriles. Conversely, treatment of H2Pcs with ReO4− employing sodium metabisulfite yielded the desired ReVO−Pc complex. Finally, reaction of H2Pcs with ReO4− and NaBH4 as reducing agent led to the formation of rhenium oxide (RexOy) nanoparticles (NPs). The NP synthesis was optimised, and the RexOy NPs were capped with folic acid (FA) conjugated with tetraaminophthalocyanine (TAPc) to enhance their cancer cell targeting ability. The cytotoxicity profile of the resultant RexOy−TAPc−FA NPs was assessed and found to be greater than 80 % viability in four cell lines, namely, MDA−MB‐231, HCC7, HCC1806 and HEK293T. Non‐cytotoxic concentrations were determined and employed in cancer cell localization studies. The particle size effect on localization of NPs was also investigated using confocal fluorescence and transmission electron microscopy. The smaller NPs (≈10 nm) were found to exhibit stronger fluorescence properties than the ≈50 nm NPs and exhibited better cell localization ability than the ≈50 nm NPs.

The synthesis of new nitrido(phthalocyaninato)molybdenum (1–4) and ‐tungsten complexes (5–7) starting from the corresponding phthalonitriles and MNCl3 (M = Mo, W) is reported. In addition, the reaction of (tBu4Pc)WN (6) with PPh3 leading, after several steps, to the diamagnetic compound (tBu4Pc)WO (7) is described. The reaction of (tBu4Pc)ReN (9) with PPh3 leads to [(tBu4Pc)ReO]2 (12), and of [(C5H11)8Pc]ReN (10) with PPh3 leads, under different conditions, to {[(C5H11)8Pc]ReO}2O (11).
