Sintesis 2,4-Dimetil-3-Pentanol
The synthesis of 2,4-dimethyl-3-pentanol involves a Grignard reaction between 2-bromobutane and 2-methylpropanal, followed by an acidic workup. The Grignard reagent, prepared by reacting magnesium with 2-bromobutane in anhydrous diethyl ether, acts as a nucleophile, attacking the carbonyl group of 2-methylpropanal. This reaction forms an alkoxide intermediate, which is then protonated by the addition of dilute acid to yield the desired product, 2,4-dimethyl-3-pentanol. The reaction is carried out under anhydrous conditions to prevent the formation of unwanted side products.
