Abstract
Official abstract text for this publication.
The present invention is a method for producing a fluorohydrocarbon represented by a structural formula (3) comprising bringing a secondary or tertiary ether compound represented by a structural formula (1) into contact with an acid fluoride represented by a structural formula (2) in a hydrocarbon-based solvent in the presence of a boron trifluoride complex. (In structural formulae (1) to (3), each of R 1 and R 2 represents an alkyl group having 1 to 3 carbon atoms, R 3 represents a hydrogen atom, a methyl group, or an ethyl group, and each of R 4 and R 5 represents a methyl group or an ethyl group, provided that R 1 and R 2 are optionally bonded to each other to form a ring structure.)
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a fluorohydrocarbon of formula (3) comprising bringing a secondary or tertiary ether compound of formula (1) into contact with an acid fluoride of formula (2) in a hydrocarbon-based solvent in the presence of a boron trifluoride complex, wherein each of R 1 and R 2 independently represents an alkyl group having 1 to 3 carbon atoms, R 3 represents a hydrogen atom, a methyl group, or an ethyl group, and R 4 represents a methyl group or an ethyl group, provided that R 1 and R 2 are optionally bonded to each other to form a ring structure, R 5 —COF (2) wherein R 5 represents a methyl group or an ethyl group, wherein R 1 to R 3 are the same as defined above. 2. The method according to claim 1 , wherein the boron trifluoride complex is a boron trifluoride ether complex. 3. The method according to claim 1 , wherein the secondary or tertiary ether compound of formula (1) is sec-butyl methyl ether or t-butyl methyl ether. 4. The method according to claim 1 , wherein the acid fluoride of formula (2) is acetyl fluoride. 5. The method according to claim 1 , wherein the fluorohydrocarbon of formula (3) is 2-fluorobutane.
