Die Duff-Reaktion ist eine Namensreaktion der Organischen Chemie und benannt nach James Cooper Duff. Die Reaktion wird zur Einführung einer Formylgruppe (
Die Formylierung findet bevorzugt in ortho-Stellung zum Elektronendonator-Substituenten statt. Ist die ortho-Position besetzt, geschieht die Formylierung in para-Position.[2]
Ein Beispiel ist die Synthese von 3,5-Di-tert-butylsalicylaldehyd:[3]
