Versuchsvorschrift

1000 g of 1-methoxy-2,7-octadiene, 500 ml of tetrahydrofuran, 500 ml of ethanol and 2.5 g of tris(triphenylphosphine)ruthenium(II) chloride were placed in a 3 l Büchi autoclave. The temperature was set to 30° C. and the autoclave was pressurized to 30 bar by means of hydrogen. The reaction was followed via the amount of hydrogen taken up and by means of GC analyses. After 6 hours, the reaction was stopped. According to GC analysis, 98% of the 1-methoxy-2,7-octadiene had reacted to form 1-methoxy-2-octene (cis and trans) with a selectivity of 89%. The 1-methoxy-2-octene was separated from solvents and catalyst by distillation.
