A method of manufacturing an aromatic vinyl ether
-
Paragraph 0075-0077, (2016/12/16)
[Problem] To provide a method for producing an aromatic vinyl ether, which can overcome disadvantages of the conventional techniques and can produce aromatic vinyl ethers having various structures safely using a simple apparatus without using any expensive catalyst. [Solution] This method for producing an aromatic vinyl ether is characterized by comprising heating an aromatic vinyl ether (1) that has such a structure that a hydrogen atom in a phenolic hydroxy group is substituted by a vinyloxyethyl group and is represented by formula (1) (wherein R represents a residue of a phenol having n phenolic hydroxy groups; and n represents an integer of 1 to 3) without any solvent or in an aprotic polar solvent in the presence of an alkali metal compound to thereby convert the aromatic vinyl ether (1) into an aromatic vinyl ether (2) that has such a structure that a hydrogen atom in a phenolic hydroxy group is substituted by a vinyl group and is represented by formula (2) (wherein R and n are as defined above).

Bis(aryloxyethyl) vinyl ethers can be prepared in high yield by using sodium hydroxide, bis(phenols), and 2-chloroethyl vinyl ether (CEVE) with a tetraalkylammonium salt phase-transfer catalyst.The displacement reaction of the bis(phenol) dianion proceeds in high yield only if both excess CEVE and base are employed.Nucleophilic displacement is considerably faster than elimination reactions involving solvent or catalyst.Small amounts of water have little effect on the reaction.The synthesis has been extended to the preparation of related monoaryloxyethyl vinyl ethers.
