The second-semester organic chemistry laboratory at this university used to rely heavily on cookbook-type experiments that included little characterization of reaction products.More research- and discovery-oriented experiments were desired to improve the course (1).Ideally the new experiments would meet several criteria:(i) use newly acquired instruments,a high-field NMR and GC-MS,to characterize the reaction products; (ii) provide illustrations of key concepts such as selectivity; (iii) allow for discussions of action mechanisms; and (iv) demonstrate principles of green chemistry (2).An experiment incorporating all of these components is described.
