Degreased magnesium turnings (84 g., 3.5 mole) were suspended in absolute ether (100 ml.). The Mg was activated with one crystal of iodine. In the course of about 3 hours, 300 g. (1.75 mole) of geranyl chloride, then 268 g. (3.5 mole) of allyl chloride in 800 ml. of ether were added dropwise. The mixture was boiled for 4 hours, then it was cooled and poured into a solution of 200 g. of NH4Cl in 1 liter of ice water. The solution was extracted with ether. The extracts were treated as usual, after concentration, they gave 384 g. of crude 6,10-dimethyl-1,5,9-undecatriene which was used without further purification.
