An efficient and novel synthesis of meso-tetraarylporphyrins is accomplished through iodine-catalyzed condensation of pyrrole, and aryl aldehydes and subsequent oxidation by air under thermal or ultraviolet (UV) irradiation conditions. The advantages of this procedure include good yields and a green nature.

meso-Tetraarylporphyrins are synthesized from pyrrole and aryl aldehydes cleanly and efficiently in one pot at room temperature using equimolar amount of CF3SO2Cl in the presence of air as oxidant. By this novel method 5,10,15,20-tetraarylporphyrins can be prepared in excellent yields. (C) 2004 Elsevier Ltd. All rights reserved.

Chlorins have been synthesized through the reduction of the corresponding porphyrins although theoretically they can be obtained from reduced macrocycle forms as porphyrinogens. A new method for the oxidation of meso-tetraarylporphyrinogens was developed generating a substantial amount of chlorin relatively to porphyrin. The structure of the porphyrinogen, particularly the presence of substituents on the meso-phenyl groups, is decisive for the final yield of chlorin. In the case of meso-tetrakis(2,6-dichlorophenyl)porphyrinogen, 92% of the corresponding chlorin is obtained. (C) 2010 Elsevier Ltd. All rights reserved.
