And the article was included in Journal of the American Chemical Society in 2000.Recommanded Product: 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol The following contents are mentioned in the article:
Carbonyl ruthenium(II) 5,10,15-tris(4-R-phenyl)-20-(4-hydroxyphenyl)porphyrins (R = Cl, Me) covalently attached to Merrifield’s peptide resin were prepared The catalyst with R = Cl was found to efficiently catalyze Cl2pyNO epoxidation of a wide variety of alkenes, including aromatic and aliphatic terminal alkenes, cis- and trans-stilbene, cyclohexene and cyclooctene, ¦Á,¦Â-unsaturated ketones, conjugated enyne, glycal, and protected ¦Á-amino alkene. Unusual selectivities were observed for the epoxidations of 1,5-cyclooctadiene, cis-1-phenyl-3-penten-1-yne (9), 3,4,6-tri-O-acetyl-
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligand design occupies a central place in organic synthesis and catalysis. Chiral compounds with high purities and ee values are often used as ligands for catalytically active metal complexes. Recommanded Product: 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol
