Fluorine-containing 3,5-OXO-1,6-heptadiene derivative and method of producing the same

摘要

A method of producing a compound represented by formula (IV), having: subjecting a compound of formula (I) to fluorination, subjecting the resultant compound to at least one of thermal decomposition and hydrolysis, and subjecting the resultant compound to thermal decomposition, to obtain the compound of formula (IV): in which R¹ and R² each independently are a hydrogen atom, a halogen atom, or a substituent; X¹ is a hydrogen atom or a halogen atom, Y is an alkoxycarbonyl group or -CH₂OCOR³, R³ is a substituent, and R^1F and R^2F each independently are a halogen atom or a fluorine-containing group.
