Synthesis and characterization of asymmetric oxyacetamide bridged porphyrin conjugates embedded with N-containing heterocycles

Autor: Ayman M. K. Sweed, Sherif S. Ragab, Yasser M. Shaker

Publikováno v: Journal of Porphyrins and Phthalocyanines. 26:648-655

In the search for photosensitizers based on 5,10,15,20-tetrakis(3-hydroxyphenyl)porphyrin (m-THPP, 1), a novel series of asymmetric A3B porphyrin molecules with oxyacetamide linkers have been synthesized. A facile synthetic route was followed through

MTHPP monoacetic ester: unexpected formation, zinc metalation, thermal and photophysical properties

Autor: Ayman M. K. Sweed, Yasser M. Shaker, Sherif S. Ragab

Publikováno v: Journal of the Iranian Chemical Society.

In the current investigation we report an unexpected methyl esterification occurred during the coupling reaction of mTHPP monoacetic acid 2 with 3-amino-1,2,4-triazole in the presence of HBTU/DIPEA. The mechanism of this unexpected methyl esterificat
