Process for producing fluorinated polyvalent carbonyl compound

A process for producing a fluorinated polyvalent carbonyl compound (5), which comprises reacting a compound of the following formula (1) with a compound of the following formula (2) to obtain a compound of the following formula (3), then reacting the compound of the formula (3) with fluorine in a liquid phase to obtain a compound of the following formula (4) and cleaving the ester bonds derived from primary and secondary alcohols in the compound of the formula (4):

• 10
• wherein each of R1, R2, R3 and R4 which may be the same or different, is a monovalent organic group;
• QH is a (m+n+p)valent organic group;
• R1F, R2F, R3F, R4F and QF are the same groups as R1, R2, R3, R4 and QH, respectively, or groups having R1, R2, R3, R4 and QH fluorinated, respectively;
• X is a halogen atom;
• otherwise, R2 and R3, or R2F and R3F, may, respectively, be connected to constitute a bivalent group;
• each of m, n and p is an integer of at least 0, provided that (m+n+p)≧2, and n and p are not 0 at the same time, and when m is 1, n is 1, and p is 0, or when m is 1, n is 0, and p is 1, QH may be a single bond, and when QH is a single bond, QF is a single bond.
