Process for the selective preparation of an optionally halogenated tertiary allyl ester which comprises reacting, at a temperature of between -20.degree. C. and 50.degree. C., an alkali metal salt of a carboxylic acid with chloromyrcene, in an inert halogenated aliphatic hydrocarbon solvent in the presence of a catalyst soluble in said solvent, the catalyst being cuprous chloride together with triethylamine hydrochloride, in which the cuprous chloride and the triethylamine hydrochloride are used in a molar ratio of 0.5 to 10% relative to chloromyrcene.
