Die Rothemund-Reaktion ebnete den Weg für die Synthese vieler verschiedener Porphyrine. Das Team um Rothemund hatte bereits bei 25 verschiedenen aliphatischen, aromatischen und heterocyclischen Aldehyden positive Ergebnisse bei der Synthese von Porphyrinen erhalten. Für die Reaktion wird Pyrrol benötigt, sowie Salzsäure als Katalysator. Als Lösungsmittel wurde Methanol genutzt. Die Reaktion findet in einem Zeitraum von 24 Stunden bei 140–150 °C statt.
