FLUOROADAMANTANE DERIVATIVE

摘要

Adamantane derivates which can be material compounds of a polymer excellent in etching resistance and having improved transmittance to light having a short wavelength, are produced by an economically advantageous process from readily available materials. A compound (10) is subjected to esterification reaction with a compound (11) to obtain a compound (12), which is subjected to fluorination in a liquid phase to obtain a compound (13), which is then subjected to hydrolysis or alcoholysis to obtain a compound (2), which is then reacted with a compound (15) thereby to obtain a compound (1). Here, A to J are -CFH- or -CF₂-; R^F is a perfluoroalkyl group or the like; X¹⁰ is F or the like; Y² is H or OH; Y³ is H or R^FCOO-; Y⁴ is H, F or R^FCOO-; Y⁵ is H, F, R^FCOO- or OH; Y⁰ is H, F, -OCOCR¹-CH₂ or OH: R¹ is a hydrogen atom, a methyl group or the like; and X¹¹ is OH or a halogen atom:
