Synthesis of Tetra(4-nitrophenyl) porphyrin and Tetra(4-aminophenyl) porphyrin
Abstract:
An improved method for synthesis of tetra (4-nitrophenyl) porphyrin (TNPP) and tetra (4-aminophenyl) porphyrin (TAPP) is reported. 4-Nitrobenzaldehyde was cyclized with pyrrole in refluxing nitrobenzene using a lactic acid catalyst and then precipited by methanol giving TNPP of 22.3% yield in high purity. Reduction of TNPP with SnCl2·2H2O in concentrated HCl gave high purity TAPP in yield of 81.5%.
