Aluminum oxide Knoevenagel reaction

Fig. 13.53. Mechanism of a Knoevenagel reaction with nitromethane. Alkaline aluminum oxide powder is sufficiently basic to deprotonate nitromethane. The small amount of the anion generated from nitromethane suffices for the addition to aldehydes to proceed. The elimination of water via an Elib mechanism follows quickly if a conjugated C=C double bond is formed, as in the present case. Fig. 13.53. Mechanism of a Knoevenagel reaction with nitromethane.
