Versuchsvorschrift

Synthesis (c): A mixture of geraniol and nerol (approximately 70:30 by weight) in the amount of 94.86 g (0.615 mol) and succinic anhydride in the amount of 20.51 g (0.205 mol) are combined at room temperature. The mixture is heated to 140° C. for 6 h while water is removed using an argon sparge. After cooling to room temperature, the mixture is placed in a Kugelrohr oven and concentrated at 80°-85° C. for 5.5 h. Purity of the product is determined by thin layer chromatography and the structure confirmed by 13C and 1H NMR.
