Synthesis of some substituted tetraarylporphyrins was written by Little, Robert G.;Anton, John A.;Loach, Paul A.;Ibers, James A.. And the article was included in Journal of Heterocyclic Chemistry in 1975.COA of Formula: C47H36N4O The following contents are mentioned in the article:
The porphyrins I (R = 2-, 3-pyridyl, p-MeCONHC6H4, 2-, 3-, 4-HOC6H4; R+ = p-MeC6H4, R = R+ = 3-pyridyl, p-MeCOC6H4, p-HOC6H4, p-BuC6H4OH) were prepared by cyclization of pyrrole with RCHO and R+CHO. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5COA of Formula: C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. A ligand is an ion or molecule, which donates a pair of electrons to the central metal atom or ion to form a coordination complex. The actual catalysts are metal complexes that are prepared from ligands and appropriate metal precursors.COA of Formula: C47H36N4O
