Synthesis of Cinnamic Acids
One of the simplest and most efficient and environmentally benign methods for cinnamic acid synthesis is based on the Knoevenagel condensation of diethylmalonate with benzaldehyde catalyzed by mixed oxides of Mg/Al, Mg–Al + Ln (Ln = Dy, Gd), or Li/Al as shown in Fig. 8.6 [140].
