Participants

Reaction Steps

20 g of ethyl 5,9,13-trimethyl-3,4-tetradecadienoate and 1 g of potassium carbonate were heated at 40° to 45°C. for 3 hours in the absence of a solvent to effect the rearrangement reaction. Then, the reaction mixture was neutralized with 4N HCl and subjected to distillation under reduced pressure. Ethyl 5,9,13-trimethyl-2,4-tetradecadienoate was obtained in a yield of 93% from a fraction boiling at 143 to 145°C. under 1 mm Hg.
