A 13C NMR spectral study of 29 arylporphyrin derivatives is presented. In all of the tetrasubstituted and trisubstituted compounds examined the ¦Á- and ¦Â-carbons exhibited the expected broadened signals. In complete contrast, the diphenylporphyrins all showed sharp ¦Á- and ¦Â-carbon peaks which facilitated structural confirmation. These observations have been correlated with differing tautomeric exchange rates. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Electric Literature of C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Catalytic transformations have become a mainstay in the toolkit of the synthetic and increasing non-synthetic chemist alike. The ligands are electron-rich and highly tunable to provide catalyst systems with a diverse scope, high stability, and reactivity.Electric Literature of C47H36N4O
