Abstract: ms-Tetra (p-alkylthiophenyl) porphyrins and ms-tetra (o-alkylthiophenyl) porphyrins(alkyl=methyl, ethyl, propyl) were synthesized by refluxing the mixture of pyrrole,and para or ortho (alkylthio) benzaldehydes in propionic acid or in acetic acid. Some metal complexes of these porphyrins were prepated by refluxing the mixture of the porphyrin and the corresponding metal salt in acetic acid or in DMF. All the porphyrins described were identified by visible spectrophotometry, nuclear magnetic resonance spectroscopy and elemental analysis.

Key words: ms-Tetra(alkylthiophenyl)porphyrin, Metalloporphyrin, Complex Synthesis
