Versuchsvorschrift
(S)-3,7-dimethyl-6-hydroxy-7-octene-1-ol (I) (10.0 g, 58.1 mmol), palladium acetate (130.0 mg, 0.579 mmol), and triphenylphosphine (1.52 g, 5.795 mmol) were placed in a 50 ml three neck distillation flask provided with a thermometer and a vacuum distilling apparatus having a side arm. Butanol (20 ml) was then added to the flask and the mixture was heated for 12 hours with stirring at a reaction temperature of 115° to 120° C. and a atmospheric pressure in a stream of nitrogen. After the reaction had terminated, the flask was evacuated to remove solvent from the reaction mixture, and the resultant was distilled to obtain 7.2 g (89° to 91° C./4 mmHg) of (S)-3,7-dimethyl-5,7-octadiene-1-ol (II). The yield was 80%.
