Abstract
We report a microwave-assisted reduction of cyclohexanone by sodium borohydride that is supported on SiO2. The reaction was completed in less than 3 minutes. Workup and analysis by GC–MS, IR, and 1H NMR was possible in a two and half-hour laboratory session. This reduction was used successfully in a second-year organic chemistry laboratory. Students were exposed to a green chemistry reaction using solid-state-supported reactants in the absence of solvent.
Supplement
Instructions for the students, notes for the instructor, and IR, 1H NMR, GC–MS, and 13C NMR spectra are available.
