Abstract

A fluorine-containing styrene monomer of the formula (2) is produced by a first, second or third process. The first process includes (a) reacting a compound of the formula (1) with a compound of the formula (3), in the presence of a metal catalyst; (b) reacting the product of the step (a) with a base; and (c) reacting the product of the step (b) with hydrogen, in the presence of a metal catalyst and a phosphine or amine, thereby producing the target styrene monomer. The second process includes reacting a compound of the formula (1) with a compound of the formula (12), in the presence of a metal catalyst, thereby producing the target styrene monomer. The third process includes reacting a compound of the formula (13) with a compound of the formula (14) or (15), in the presence of a base, thereby producing the target styrene monomer. 1

Dependent claims

A process for producing a fluorine-containing, polymerizable styrene monomer represented by the formula (2), the process comprising the steps of:

(a) reacting a compound represented by the formula (1) with a compound represented by the formula (3), in the presence of a metal catalyst, thereby producing a compound represented by the formula (4);
(b) reacting the compound represented by the formula (4) with a base, thereby producing a compound represented by the formula (5);
and
(c) reacting the compound represented by the formula (5) with hydrogen, in the presence of a metal catalyst and one of a phosphine and an amine, thereby producing the fluorine-containing, polymerizable styrene monomer represented by the formula (2),
21
where R1 a methyl group or trifluoromethyl group,
R2 is a hydrogen atom, an alkyl group, or an aryl group, each of the alkyl group and the aryl group independently having a carbon atom number of 1 to 25, independently having a straight-chain, branched or ring form, and independently and optionally having at least one of a fluorine atom, an oxygen atom, and a carbonyl bond,
R3 is a halogen atom or alkylsulfonyl group, and
n is 1 or 2,
22
where R1, R2 and n respectively correspond to those of the formula (1),
23
where R4 is C(OH)R5R6 or SiR7R8R9 where each of R5 to R9 independently has a carbon atom number of 1 to 25, independently is an alkyl group or aryl group, and independently and optionally has, in place of a carbon atom, at least one of a hetero atom and a substituent, and where each of R5 and R6 independently and optionally contains a fluorinated alkyl group,
24
where R1, R2 and n respectively correspond to those of the formula (1), and R4 corresponds to that of the formula (3),
25
where R1, R2 and n respectively correspond to those of the formula (1).
