Efficient synthesis of meso-tetraarylporphyrins using i2 as catalyst and ibx as oxidant

meso-Tetraarylporphyrins are synthesized from pyrrole and substituted benzaldehydes by a catalytic amount of I2 as catalyst and o-iodoxybenzoic acid (IBX) as oxidant in two steps and one flask. The advantages of this method include the use of inexpensive and easily available catalyst, avoidance of heavy consumption of CH2Cl2, innocuous oxidant, and good yields.

Synthesis and characterization of tetraarylporphyrins in the presence of nano-TiCl4·SiO2

[MediaObject not available: see fulltext.] Synthesis of tetraarylporphyrins by the coupling of an aromatic aldehyde and pyrrole using nano-TiCl4·SiO2 as mild, inexpensive, and highly efficient catalyst is studied in the present article.

Synthesis of meso-tetraphenyl porphyrins via condensation of dipyrromethanes with N-tosyl imines

A new synthetic route for the synthesis of 5,10,15,20-tetraphenyl porphyrins has been developed based on the reaction of 5-substituted dipyrromethanes with N-tosyl imines in the presence of a metal triflate catalyst. meso-Substituted tetraphenyl porphyrins were synthesized in a two-step process. The first step of the method is the metal triflate-catalyzed condensation of 5-substituted dipyrromethanes with N-tosyl imines to form a porphyrinogen intermediate and the second step is the oxidation of the porphyrinogen to porphyrin. The method was applied to the synthesis of trans-A2B2-tetraarylporphyrins and the products were obtained with only a trace amount of one scrambling product. The synthesis of two important building blocks for porphyrin synthesis, mono and di-sulfonamide alkylated 5-substituted dipyrromethanes, was achieved by the addition of 5-substituted dipyrromethane to N-tosyl imine. The application of mono and di-sulfonamide alkylated 5-substituted dipyrromethanes in '2+2' porphyrin formation reactions is presented.
