The Pechmann Reaction
Michael S. Holden and R. David Crouch
Dickinson College, Department of Chemistry, P .O. Box 1773, Carlisle, PA 17013-2896

Abstract
A solid acid-catalyzed version of the Pechmann reaction for the synthesis of coumarins is described. The Pechmann reaction is a multiple-transformation process which is not a part of the normal organic chemistry curriculum. However, each transformation (hydroxyalkylation, transesterification, dehydration) is one that can be understood by students, and by applying the known mechanisms in sequence, the correct product can be predicted.
