Abstract. Herein we report a fast, solventless aldol condensation reaction using trans-cinnamaldehyde and a variety of ketones (1-indanone, acetophenone, a-tetralone). The reactions yield highly colored solids which may be analyzed by melting point, thin layer chromatography (TLC), infrared spectroscopy (IR) and ultraviolet-visible (UV) spectroscopy. Moreover, nuclear magnetic resonance (NMR) analysis (1H NMR, 13C NMR) allows for a more advanced product examination that can be adopted for instructional purposes in an undergraduate organic chemistry course.
