- NMR study of kinetic HH/HD/DH/DD isotope effects on the tautomerism of acetylporphyrin: Evidence for a stepwise double proton transfer
-
The kinetic HH/HD/DH/DD isotope effects of an intramolecular reversible nondegenerate double proton transfer reaction are described. The molecule studied is 8-acetyl-3,13,17-tris[2-(methoxycarbonyl)ethyl]-2,7,12,18-tetramethyl-(21H,23H)- Porphyrin (acetyl

- TOTAL SYNTHESIS OF -PROTOPORPHYRIN-IX DIMETHYL ESTER
-
A total synthesis of the protoporphyrin-IX dimethyl ester (1) in which all four nitrogen atoms are 99percent enriched with 15N is described.The source of 15N was commercially available sodium nitrite, and the porphyrin was constructed stepwise throug
