Abstract
Provided is a method for industrially advantageously producing a fluorinated hydrocarbon (3). The disclosed method for producing a fluorinated hydrocarbon represented by formula (3) includes bringing into contact, in a hydrocarbon-based solvent, a secondary or tertiary ether compound represented by formula (1) below with an acid fluoride represented by formula (2) in the presence of lithium salt or sodium salt (in the formulae, R1 and R2 each represent a C1-3 alkyl, and R1 and R2 may be bonded to each other to form a ring structure; R3 represents a hydrogen atom, methyl, or ethyl; and R4 and R5 each represent methyl or ethyl).
Claims5
A method for producing a fluorinated hydrocarbon represented by formula (3) below, wherein an ether compound represented by formula (1) below and an acid fluoride represented by formula (2) below are brought into contact with each other in a hydrocarbon-based solvent, in the presence of lithium salt or sodium salt,
- (in formula (1) above, R1 and R2 each independently represent an alkyl group having 1 to 3 carbon atoms, R3 represents a hydrogen atom, a methyl group or an ethyl group, and R4 represents a methyl group or an ethyl group;
- and R1 and R2 may be bonded to each other to form a cyclic structure),
- R5—COF (2)
- (in formula (2) above, R5 represents a methyl group or an ethyl group),
- (in formula (3) above, R1 to R3 represent the same meanings as described above).
