实验步骤: A mixture of 172 g of α-methyl-allylidene diacetate and 160 g of p-tert.amyl-benzene is allowed to drop in to a mixture, cooled to -10° C., of 637 g of p-tert.amyl-benzene, 211 g of titanium tetrachloride and 3 g of boron trifluoride etherate while stirring over a period of 1.5 hours. The mixture is subsequently stirred at -10° C. for 45 minutes and then poured on to a mixture of 800 ml of ice-water and 140 ml of concentrated hydrochloric acid in order to hydrolyse the titanium tetrachloride. The organic layer is separated, washed neutral with water and 5% sodium bicarbonate solution, dried over sodium sulphate and the excess p-tert.amyl-benzene is distilled in a water-jet vacuum. (Boiling point 108° C./20 Torr). The residue, crude 3-(p-tert.amyl-phenyl)-2-methyl-1-propenyl acetate, is taken up in 190 ml of methanol, treated with a solution of 80 g of potassium carbonate in 145 ml of water and heated at reflux with intensive stirring until the saponification has been completed. The methanol is distilled and the organic phase is separated and distilled. There is obtained pure 3-(p-tert.amyl-phenyl)-2-methyl-propionaldehyde of boiling point 109°-111° C./0.06 Torr. The mixture is subsequently stirred at -10° C. for 45 minutes The organic layer is separated washed neutral with water and 5% sodium bicarbonate solution dried over sodium sulphate the excess p-tert.amyl-benzene is distilled in a water-jet vacuum treated with a solution of 80 g of potassium carbonate in 145 ml of water heated at reflux with intensive stirring until the saponification The methanol is distilled the organic phase is separated distilled
