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(—CH—OCO—R)  (3A-1)A(—CF—OCO—R)  (4A-1)A(—COOR)  (3A-2)A(—COOR)  (4A-2)A(—COF)  (5A)A(—OCO—R)  (3B)A(—OCO—R)  (4B)A(—OH)  (5B)provided that the carbon atom in adamantane to which —OCO—Ris 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, Ais a group having at least one of hydrogen atoms in the group A substituted by a fluorine atom, and Ris a fluorinated monovalent organic group.
