The reactions of unsym. porphyrins 5,10,15-tris(4-tolyl)-20-(3-R-4-R’-phenyl)porphyrins (R’ = OH; R = H, 1; R = Me, 2) with Ni(OAc)2¡¤4H2O in boiling DMF produce porphyrin complexes (3 and 4). From the reactions of free porphyrin ligands 1 and 2 with hexachlorocyclotriphosphazatriene, N3P3Cl6, the new free porphyrino-phosphazene derivatives (R’ = O-P3N3Cl5, 5 and 6) were obtained. However, the reactions of N3P3Cl6 with porphyrin complexes (3 and 4) afford the new nickel porphyrino-phosphazene complexes (R’ = O-P3N3Cl5, 7 and 8). In the literature there are a few examples of the porphyrino-phosphazene architectures. The structural studies of all the compounds were made by elemental analyses, MS, FTIR, 1H NMR, 31P NMR and UV-visible techniques. The cyclic voltammograms (CVs) were examined in acetonitrile (MeCN) containing 0.1M tetrabutylammonium-tetrafluoroborate (TBATFB) to study the surface attachment properties at the glassy carbon electrode (GCE) and the influence of the presence of metal cations in the porphyrin ring. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Quality Control of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligands are classified based on the number of lone pair electrons available for the central metal atom, size and charge like anionic, cationic, neutral, monodentate, bidentate, polydentate ligands. The ability of ligands to engender a variety of useful properties of organometallic complexes is the major enabling force for the discovery of new catalytic reactions, activation of small molecules, dramatically enhanced reactivity.Quality Control of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol
