Direct, oxidant-mediated intramolecular coupling of pentapyrromethanes afforded 5-aryl-5-(2%-pyrryl)-10,15,20-triarylporphyrin (phlorins) as single products. The outcome of the reaction is comparable with the oxidative coupling of tetrapyrromethanes. Treatment of obtained phlorins with trifluoroacet
