Acid-catalyzed porphyrin formation from meso-aryltripyrromethanes and $25-bis({alpha}$, - hydroxyl - $alpha$ -phenyl) methylfuran is studied. The condensation resulted in selective scrambling of tripyrromethanes when the condensation was carried out with catalytic amounts of $BF_3$ in methylene chloride. But the reaction carried out with p-TsOH or $BEt_3$ catalysts in the presence of $NH_4Cl$ in acetonitrile, single porphyrin product was isolated without scrambling of starting tripyrromethane. The yields of porphyrin in these studies were somewhat lower than those of 2+2 condensations or aldehyde-pyrrole condensations.
