Patent ID: 6943271

Claim:
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), where R 1 a methyl group or trifluoromethyl group, R 2 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, R 3 is a halogen atom or alkylsulfonyl group, and n is 1 or 2, where R 1 , R 2 and n respectively correspond to those of the formula (1), where R 4 is C(OH)R 5 R 6 or SiR 7 R 8 R 9 where each of R 5 to R 9 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 R 5 and R 6 independently and optionally contains a fluorinated alkyl group, where R 1 , R 2 and n respectively correspond to those of the formula (1), and R 4 corresponds to that of the formula (3), where R 1 , R 2 and n respectively correspond to those of the formula (1).
