Title:
フルオロアルキン化合物の製造方法
Document Type and Number:
Japanese Patent JP7343796
Kind Code:
B2
Abstract:
A fluoroalkyne compound can be efficiently synthesized from a fluoroalkane compound by a method for producing a fluoroalkyne compound represented by formula (1): R1C≡CR2 (1)wherein R1 and R2 are the same or different and each is a fluorine atom or a fluoroalkyl group,the method comprising subjecting a fluoroalkane compound represented by formula (2): R1CHX1CFX2R2 (2)wherein R1 and R2 are as defined above; and X1 is a fluorine atom and X2 is a hydrogen atom, or X1 is a hydrogen atom and X2 is a fluorine atom, to a dehydrofluorination reaction in the presence of an ether solvent,the method satisfying at least one requirement selected from the group consisting of the following:(I) the fluoroalkyl group is a C1-C4 fluoroalkyl group, and(II) the ether solvent is a chain ether compound, and the dehydrofluorination reaction is performed in the presence of the solvent containing a chain ether and a base comprising a hydroxide and/or alkoxide of an alkali metal and/or alkaline earth metal.
