4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Attachment of the ligand to the metal may be through a single atom, in which case it is called a monodentate ligand, or through two or more atoms, in which case it is called a didentate or polydentate ligand. Replacing precious metals with cheaper and more environmentally friendly metals is regarded as a highly desirable goal in the field of catalysis.Application In Synthesis of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol

Synthesis, characterization, and variable-temperature 1H- and 19F-NMR investigations of cerium(IV) double-deckers derived from monofunctionalized tetraarylporphyrins was written by Buchler, Johann W.;Eiermann, Volker;Hanssum, Helmut;Heinz, Georg;Rueterjans, Heinz;Schwarzkopf, Markus. And the article was included in Chemische Berichte in 1994.Application In Synthesis of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol The following contents are mentioned in the article:

The synthesis of a Ce(V) bisporphyrinate 1b starting from p-(hydroxyphenyl)tris(p-tolyl)porphyrin 2b is described. Derived from 2b by substitution of the phenolic OH group, the monofunctionalized tetraarylporphyrins 2c–f and their Ce(IV) sandwich complexes 1c–f were synthesized. The complexes are characterized by UV/visible, IR, and 1H-NMR spectroscopy. 19F-NMR spectra of 1f show a vicinal and a transversal isomer due to the rigid square-antiprismatic coordination geometry of Ce(IV) bisporphyrinates. Variable-temperature 1H- and 19F-NMR spectra were recorded to study the rotational rigidity of the double-decker system. The spectra show that the vicinal and transversal isomers are stable up to 140¡ã, i.e. rotation of the 2 porphyrin macrocycles with respect to each other does not occur. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Application In Synthesis of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol).
