Abstract
A decarboxylation reaction of a (3-methyl-3-butenyl)malonic acid dialkyl ester, carried out by heating in the presence of water and a base, produces an alkyl 5-methyl-5-hexenoate. The decarboxylation reaction produces the alkyl 5-methyl-5-hexenoate inexpensively and effectively. The base can optionally be a tertiary amine compound or a heterocyclic amine compound. Producing the alkyl 5-methyl-5-hexenoate can optionally further include removing an alcohol.
