Abstract

An object of the present disclosure is to provide a method for producing an organic compound, and a composition. The object is achieved by a method for producing a compound represented by formula (1): wherein X represents —O—, an optionally substituted imino group, or —S—, R 1 represents a hydrogen atom or a hydrocarbyl group optionally having at least one substituent, and R 2 represents a hydrogen atom or a monovalent organic group, or R 1 and R 2 , together with X and one carbon atom respectively adjacent to R 1 and R 2 , may form a heterocyclic ring optionally having at least one substituent, R 3 represents a hydrogen atom or a monovalent organic group, and R 4 represents —CF 2 CH 3 or —CH 2 CHF 2 ; the method including step A of reacting a compound represented by formula (2): wherein the alphabetical symbols are as defined above, with vinylidene fluoride under light irradiation.

Claims (8)

1 . A composition comprising a fluorine-containing olefin, the composition comprising:

(1) a fluorine-containing olefin, the fluorine-containing olefin excluding vinylidene fluoride, and

(2) a liquid medium,

wherein at least a portion of the fluorine-containing olefin in a form of fine bubbles is dispersed in the liquid medium; and

wherein the fine bubbles are in such a form that the percentage of the number of bubbles having a particle size within a range of 5 nm to 100 μm is 90% or more of the total number of the bubbles.

2 . The composition comprising the fluorine-containing olefin according to claim 1 , wherein the fluorine-containing olefin is a compound represented by formula (3):

wherein R a1 , R a2 , R a3 , and R a4 are the same or different and each represent a hydrogen atom, a fluorine atom, a chlorine atom, or a fluoroalkyl group, with the proviso that of R a1 , R a2 , R a3 , and R a4 , at least one is a fluorine atom.

3 . The composition comprising the fluorine-containing olefin according to claim 1 , wherein the liquid medium comprises at least one member selected from the group consisting of water an organic solvent that is a poor solvent for the fluorine-containing olefin represented by formula (3).
