Versuchsvorschrift
In a three-necked flask provided with reflux condenser and magnetic stirrer, 0.5 g (3.8 mmol) of cinnamaldehyde (trans-3-phenyl-2-propanol) and 12 g of isopropyl alcohol (for a starting material/catalyst ratio=1:1) or 1.5 g (11.3 mmol) of cinnamaldehyde and 36 g of isopropyl alcohol (starting material/catalyst=3:1) were refluxed under argon with 0.5 g of catalyst and 1.5 g of dodecane (as GC standard). After the end of the reaction time, the reaction mixture was analyzed by gas chromatography and the yield was determined. The results are summarized in Table 2 below:
