Method for producing difluoro ester compound

A method for producing a difluoro ester compound represented by the following formula (2), which comprises fluorinating an ester compound represented by the following formula (1) by reacting it with an electrophilic fluorinating agent in the presence of a basic compound and in the absence of a metal compound reactant:

• (wherein R1 is a group selected from the group consisting of a C1-30 alkyl group which may have a substituent, a C3-30 cycloalkyl group which may have a substituent, a C4-30 cycloalkenyl group which may have a substituent (provided that the carbon atom adjacent to the carbon atom at the α-position of the carbonyl group forms no double bond), a C2-30 alkynyl group which may have a substituent, and a C8-30 cycloalkynyl group which may have a substituent, and R2 is a C1-30 hydrocarbon group which may have a substituent, or R1 and R2 are bonded to form an alkylene group which forms, together with —C—C(O)—O—, a lactone ring which has from 3 to 8 carbon atoms in the ring and which may have a substituent.).
