Results Methanol solutions of acetone, 2-butanone, 3-methyl-2-butanone, or 4-heptanone were allowed to react with 1 or 2 equiv of chlorine at 20-50" C. Chlorine is bubbled into the reaction mixture. After a short induction period, the yellow solution becomes colorless and the temperature increases. When addition of 1 equiv of chlorine is complete, the solution turns yellow and cooling of the reaction is necessary. The reaction products at this point ...
