Abstract

An efficient synthetic method of substituted meso-tetraphenylporphyrins with better isolated yields was proposed by using propionic acid, valeric acid and m-nitrotoluene as mixed-solvent systems. The porphyrin yields in mixed solvent systems were obviously higher than those in the single propionic acid or valeric acid as solvents. The further investigation showed that the acidity, polarity, viscosity and the property of oxidant played an important role to the synthesis of porphyrin. Compared with other oxidants, m-nitrotoluene as an excellent oxidant could completely transform tetraphenylporphyrinogen to tetraphenylporphyrin. © ARKAT-USA, Inc.
