Abstract

Fluorine substituted cyclohexene derivatives are prepared which is useful for intermediates in synthesizing terpene compounds or active components of agricultural agents and medicines, by reacting 4-trifluoromethyl-3-penten-2-one with ethyl acetoacetate. 4-trifluoromethyl-3-penten-2-one which is formed from acetylmethylene triphenylphosphorane and trifluoroacetone is reacted with ethyl acetoacetate in benzene in the presence of sodium ethoxide at 60 deg. C to produce 3,5-dimethyl-5-trifluoromethyl-2-cyclohexen-1-one, which is subsequently reacted with methyl magnesium iodide and ferric chloride to obtain 3,5-dimethyl-5-trifluoromethyl-3-cyclohexen-1-one.
