- W1981437056 abstract "Procedures for the synthesis of new partially-substituted mesotetraphenylporphyrins (TPP's) are described. The 5-(3-nitrophenyl)-10,15,20-triphenylporphyrin is the primary product from a 1:2:3 molar ratio of m-nitrobenzaldehyde, benzaldehyde and pyrrole. The crude reaction product also contained TPP, 5,10-bis-(3-nitrophenyl)-15,20-diphenylporphyrin, 5,15-bis(3-nitrophenyl)-10,20-diphenylporphyrin, and 5,10,15-tris-(3-nitrophenyl)-20-phenylporphyrin. The crude mixture of m-nitrophenylporphyrins was reduced to a mixture of the corresponding amino derivatives, which was separated into TPP, 5-(3-aminophenyl)-10,15,20-triphenylporphyrin, 5,10-bis(3-aminophenyl)-15,20-diphenylporphyrin, and 5,15-bis(3-aminophenyl)-10,20-diphenylporphyrin. The products were characterized by uv-visible and ir spectrophotometry, and by high resolution nmr spectroscopy and mass spectroscopy." @default.
