Synthesis of 2-Methyl-4-heptanone: An Ant Alarm Pheromone.
Abstract 2-methyl-4-heptanone is an ant pheromone used to alarm fellow ants. The synthesis described in this article is greeted with interest by students.
Grignard initiation should typically occur in five minutes or less (get help from you instructor if not). 3. Remember that you are dealing with highly exothermic reactions! 4. Transfer the crude alcohol to a labelled, pre -weighed vial. Obtain the mass of the crude alcohol next week.
The synthesis of 2-methyl-4-heptanone using disubstituted alkene containing four carbon atoms as starting material involves several steps. The step-1 (trans-2-butene to 1-butanal) of the reaction scheme is illustrated below.
