Abstract
The reaction of morpholine with t-butyl acetoacetate in a one-to-one molar ratio will produce the corresponding enaminoester under kinetic control conditions and the ketoamide under thermodynamic control conditions. Students can identify the reaction products using NMR, IR, and GC-MS, but certain pitfalls to be avoided in this identification are pointed out. Molecular modeling of each of the two possible products gives the same results as the laboratory experiment. The possible use of microwave radiation is discussed.

Using Molecular Representations To Aid Student Understanding of Stereochemical Concepts
Michael Abraham, Valsamma Varghese, and Hui TangJournal of Chemical Education2010 87 (12), 1425-1429Using Molecular Representations To Aid Student Understanding of Stereochemical Concepts
Michael Abraham, Valsamma Varghese, and Hui TangJournal of Chemical Education2010 87 (12), 1425-1429Stereochemistry is an important topic in organic chemistry. It is also a difficult topic for students to learn. This study investigated the relative effectiveness on students’ understanding of three kinds of molecular representations of stereochemistry ...

Jack R. WaasJournal of Chemical Education2006 83 (7), 1017Enthalpy changes corresponding to the gas phase heats of dissociation of 12 organic halides were calculated using two semiempirical methods, the Hartree–Fock method, and two DFT methods. These calculated values were compared to experimental values where ...
