Abstract
The present invention provides a process A1 for producing a compound (5A), which comprises fluorinating a compound (3A-1) by liquid phase fluorination to a compound (4A-1), followed by a decomposition reaction of an ester bond; a process A2 for producing a compound (5A), which comprises fluorinating a compound (3A-2) by liquid phase fluorination to a compound (4A-2), followed by a decomposition reaction of an ester bond; and a process B for producing a compound (5B), which comprises fluorinating a compound (3B) by liquid phase fluorination to a compound (4B), followed by hydrolysis or alcoholysis. Further, the present invention provides a compound (5A) wherein n is 2 to 4, and a compound (5B) wherein n is 3 or 4.A(—CH2—OCO—R)n (3A-1)Af(—CF2—OCO—Rf)n (4A-1)A(—COOR)n (3A-2)Af(—COORf)n (4A-2)Af(—COF)n (5A)A(—OCO—R)n (3B)Af(—OCO—Rf)n (4B)Af(—OH)n (5B)provided that the carbon atom in adamantane to which —OCO—Rf is bonded, is a tertiary carbon atom, A is a n-valent group having n hydrogen atoms in adamantane converted to connecting bonds, R is a fluorinated monovalent organic group, n is an integer of from 1 to 4, Af is a group having at least one of hydrogen atoms in the group A…
