摘要： An object of the present invention is to provide a vinyl ether, a simple method for producing the vinyl ether, a haloether used for producing the vinyl ether, and a method for producing the vinyl ether.
The object can be achieved by producing a haloether by a method comprising step 1a of allowing a compound represented by formula (1):
R1O−Y+ (1)
wherein
Y+ represents a cation and R1 is an organic group,
to react, in the presence of a halogenating agent, with a compound represented by formula (2a):
wherein
R2a and R3a each independently represent H or an alkyl group,
R4a represents H, a halogen, or an organic group,
and X1a represents a halogen other than F.-

摘要： An object of the present invention is to provide, for example, a novel method for synthesizing a fluorovinyl ether compound from a fluorine-containing vinyl compound. This problem is solved by a method for producing a compound represented by formula (1):
wherein
Ra1 is a hydrogen atom, a halogeno group, an alkyl group, a fluoroalkyl group, or an aromatic group optionally having one or more substituents,
Rf is a fluoro group or a perfluoroalkyl group,
Ra2 is a hydrogen atom, a halogeno group, an alkyl group, a fluoroalkyl group, or an aromatic group optionally having one or more substituents, or
(i) Ra1 and Ra2, (ii) Ra1 and Rf, or (iii) Rf and Ra2 may be linked to each other,
Rb1 is Rs,
Rb2 is a hydrogen atom or Rs,
Rb3 is a hydrogen atom or Rs, or
two or three of Rb1, Rb2, and Rb3, taken together with the adjacent carbon atom, may form a ring optionally having one or more substituents, and
Rs, in each occurrence, is the same or different and represents a hydrocarbon group optionally having one or more substituents, the method comprising
step A of reacting a compound represented by formula (2):
wherein
Rx is a leaving group, and
other symbols are as defined above,
with a compound represented by formula (3):
wherein the symbols in the formula are as defined above,
