실험 절차
A mixture of cyclohexanecarboxaldehyde ((10 mL, 0.825 mol), allyl alcohol (60 mL, 98% purity, 0.882 mol), benzene (15 mL), and p-toluenesulfonic acid monohydrate (0.120 g, 0.63 mmol) was heated from 130° C. to 180° C. in an oil bath, under a Vigreaux distillation column, topped by a Dean-Stark trap. After 15 hour no more water was added over the 15 mL collected in the trap, and the reaction was judged completed. Subsequent distillation of the reaction crude gave 98 g (78% yield) of 1-allyl-cyclohexanecarboxaldehyde as a colourless liquid (b.p. 69-71° C./5 mm Hg).
