Participants

Reaction Steps

30.9 g 3,7-dimethyl-1-octin-3-ol, 28.9 g isopropenyl methyl ether and 60 ml n-heptane were initially introduced into a 250 ml flask and 25 mg pyridinium toluene-4-sulfonate were then added. The reaction mixture was stirred under reflux for 7 hours. During this period of time, 14.4 g isopropenyl methyl ether and 25 mg pyridinium toluene-4-sulfonate were added in two portions. When the reaction had ended, the solution was evaporated. The residue was distilled in vacuo. 31.9 g 6,10-dimethyl-4,5-undecadien-2-one were obtained, which corresponds to a yield of 82%.
