Abstract
A process for preparing 6-chloro-2-hexanone which comprises the steps of (a) oxidizing methylcyclopentane with ozone in the presence of a carboxylic acid and for a sufficient period of time to form 1-methylcyclopentanol; (b) reacting said 1-methylcyclopentanol with a suitable amount of an alkali metal hypochlorite in the presence of a carboxylic acid to form 1-methylcyclopentyl hypochlorite; and (c) heating said 1-methylcyclopentyl hypochlorite for a sufficient period of time to form 6-chloro-2-hexanone.
