Abstract
2-methylhept-2-ene-6-one is prepared by forming a mixture of acetone, 1-chloro-3-methylbutene-2 and NaOH or KOH, in the molar proportions 1-5:1:0,25-3, keeping the reactants well mixed at 0-80 DEG C for 1/2 -8 hours, and isolating the methylheptenone produced. Instead of acetone, base-catalysed condensation products of acetone, such as diacetone alcohol, may be used. 1-chloro-3-methylbutene-2 (and 3-chloro-3-methylbutene-1) are prepared by the addition of concentrated HCl to isoprene.
