The Dibenzalacetone Reaction Revisited
Leslie A. Hull
Department of Chemistry, Union College, Schenectady, NY 12308
Cover
February 2001
Vol. 78 No. 2
p. 226
Abstract
A modification of a classic experiment is described that incorporates a discovery approach to organic synthesis. Groups of students are assigned target molecules of the dibenzalketone type and are given a sample procedure for the parent dibenzalacetone reaction. They are asked to design a synthesis of their target based on the model reaction and to modify the model reaction so it will work for their synthesis. They show they have synthesized the target with 1H NMR.
Supplement
Instructions for students, notes for the instructor, sample NMR spectra, and equipment and reagent lists are available.
