Abstract
The invention relates to a novel octafluorotricyclodecane derivative represented by the general formula (1),
where R1 is a hydrogen atom, a halogen atom, a hydrocarbon group or a halogenated hydrocarbon group, m is 0 or 1, and R2 is represented by the general formula (2),
where R3 is a hydrogen atom or a hydrocarbon group optionally having a substituent. This octafluorotricyclodecane derivative may be useful as a monomer for producing various functional polymers or as a raw material of the same.
Description
- The present invention relates to novel fluorine-containing cycloalkane derivatives, which are useful as monomers for producing various functional polymers (having functions of water-repellency, oil-repellency, low water absorption, heat resistance, weatherability, corrosion resistance, transparency, photosensitivity and the like) and useful as raw materials of the same, and processes for producing such derivatives.
- Aliphatic cyclic compounds, obtained by bonding a hydroxyl group to a ring (e.g., adamantane and bicycloalkane), have been used as monomers for producing functional polymers or as raw materials of the same. There is, however, a recent demand for novel monomers or their raw materials for providing superior functional polymers.
- It is therefore an object of the present invention to provide a novel fluorine-containing cycloalkane derivative (e.g., an octafluorotricyclodecane derivative), which may be useful as a monomer for producing various functional polymers (having functions of water-repellency, oil-repellency, low water absorption, heat resistance, weatherability, corrosion resistance, transparency, photosensitivity and the like) or as a raw material of the same.
- It is another object of the present invention to provide a process for producing such novel fluorine-containing cycloalkane derivative.
-
-
- where R3 is a hydrogen atom or a hydrocarbon group optionally having a substituent.
-
-
- where R1 is defined as above,
- R3COOH (5)
- where R3 is defined as above.
-
-
- According to the present invention, there is provided a third process for producing an octafluorotricyclodecane derivative represented by the general formula (4). The third process comprises (a) conducting a rearragement reaction of an epoxy compound represented by the formula (7), thereby obtaining a ketone represented by the formula (9); (b) reacting said ketone with an organic metal compound represented by the general formula R1MX where R1 is a hydrogen atom, a hydrocarbon group or a halogenated hydrocarbon group, M is a metal, and X is a halogen atom, thereby obtaining a product; and (c) hydrolyzing said product into said octafluorotricyclodecane.
- It is possible to efficiently produce the respective target octafluorotricyclodecane derivatives by the first to third processes.
- As stated above, R1 in the general formula (1) is a hydrogen atom, a halogen atom, a hydrocarbon group or a halogenated hydrocarbon group. This halogen atom may be fluorine, chlorine or bromine. Examples of the hydrocarbon group are C1-C20 hydrocarbon groups, such as methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, sec-butyl group, tert-butyl group, cyclopentyl group, cyclohexyl group, phenyl group, benzyl group, and phenethyl group. Of these, C1-C10 hydrocarbon groups are preferable, more preferably C1-C4 hydrocarbon groups. Examples of the halogenated hydrocarbon group are those obtained by partially or fully replacing hydrogen atoms of the above alkyl groups with halogen atoms, such as trifluoromethyl group, 2,2,2-trifluoroethyl group, 1,1,1,3,3,3-hexafluoroisopropyl group.
-
- where each of R4, R5, and R6 is independently a hydrogen atom, a halogen atom, or a hydrocarbon group optionally having a substituent, and n is an integer of 0-8. This halogen atom may be fluorine, chlorine or bromine. This hydrocarbon group is preferably selected from C1-C20 hydrocarbon groups, such as methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, sec-butyl group, tert-butyl group, cyclopentyl group, cyclohexyl group, phenyl group, benzyl group, and phenethyl group. Of these, C1-C10 hydrocarbon groups are preferable, more preferably C1-C4 hydrocarbon groups. Examples of the optional substituent are acyl group, allyl group, alkoxyl group, alkoxycarbonyl group, carboxyl group, carbonyl group, hydroxyl group, vinyl group, and nitrile group.
- Concrete examples of R2 are vinyl group, allyl group, acryloyl group and methacryloyl group.
- The process for producing the octafluorotricyclodecane derivative represented by the general formula (1) will be described in detail in the following.
- It is possible to produce the target octafluorotricyclodecane derivative represented by the general formula (1) from a starting material of 2,3,3,4,4,5,5,6-octafluorotricyclo[5.2.1.02,6]-8-decene by using the first, second or third process via an intermediate such as an epoxy derivative represented by the formula (7), a ketone derivative represented by the formula (9), and an alcohol derivative represented by the formula (4) or (8). In other words, each starting material, represented by the formula (4) or (7), of the first and third processes can be produced from 2,3,3,4,4,5,5,6-octafluorotricyclo[5.2.1.02,6]-8-decene
- In the invention, the process for synthesizing the octafluorotricyclodecane derivative (an epoxy compound) represented by the formula (7) is not particularly limited. For example, it can be synthesized by treating 2,3,3,4,4,5,5,6-octafluorotricyclo[5.2.1.02,6]-8-decene with a peracid in a solvent to proceed an epoxidation, as in the second process. This solvent is not particularly limited, so long as it can dissolve 2,3,3,4,4,5,5,6-octafluorotricyclo[5.2.1.02,6]-8-decene and the peracid. Exemplary solvents are methylene chloride, diethyl ether, and tetrahydrofuran. Examples of the peracid are peracetic acid, metachloroperbenzoic acid and monoperoxyphthalic acid. The temperature and the period of time for conducting the epoxidation may be suitably selected depending on the reagent types and the like. It is preferably conducted at a temperature of 0-100° C. for 1-48 hr.
- In the invention, the process for synthesizing the octafluorotricyclodecane derivative (a ketone compound) represented by the formula (9) is not particularly limited. For example, it can be synthesized by a rearrangement reaction of the epoxy compound represented by the formula (7) using an acid catalyst, as in the third process. Examples of this acid catalyst are a complex of boron trifluoride and diethyl ether, Lewis acids (e.g., magnesium bromide), and mineral acids. It is possible to use a solvent in the rearrangement reaction. This solvent is not particularly limited, so long as it is inert in the reaction. Its examples are diethyl ether and benzene. The temperature and the period of time for conducting the rearrangement reaction may be suitably selected depending on the reagent types and the like. It is preferably conducted at a temperature of 0-100° C. for 1-48 hr.
- In the invention, the process for synthesizing the octafluorotricyclodecane derivative (an alcohol compound) represented by the formula (8) is not particularly limited. For example, it can be synthesized through a hydration of 2,3,3,4,4,5,5,6-octafluorotricyclo[5.2.1.02,6]-8-decene with an acid aqueous solution. As another example, it can be synthesized by reducing the epoxy compound represented by the general formula (7), as in the second process. This reduction can be conducted by hydrogenating this epoxy compound with a metal hydride (e.g., lithium aluminum hydride, boron hydride, sodium hydride, and lithium hydride).
- As shown in the third process, it is possible to synthesize the tertiary alcohol compound represented by the general formula (4), where R1 is not a hydrogen atom nor a halogen atom, by reacting the ketone compound represented by the formula (9) with an organic metal compound in an organic solvent, followed by hydrolysis with water. This organic metal compound may be a Grignard's reagent or an organic lithium compound. This Grignard's reagent is represented by the general formula R1MX where R1 is defined above, but is not a halogen atom; M is a metal (preferably magnesium); and X is a halogen (preferably chlorine, bromine or iodine). An example of this Grignard's reagent is an alkylmagnesium halide. The organic solvent is not particularly limited as long as it is inert in the reaction. Its examples are diethyl ether, tetrahydrofuran and hexane. Concrete examples of the organic metal compound are ethylmagnesium bromide and butyl lithium. The amount of the organic metal compound used in the reaction may be one to two equivalents per equivalent of the ketone compound. The temperature and the period of time for conducting the reaction of the ketone compound may be suitably selected depending on the organic metal compound type and the like. It is preferably conducted at a temperature of from −50 to 100° C. for about 3-48 hr.
- As shown in the first process, it is possible to produce the octafluorotricyclodecane derivative (an ester compound) represented by the general formula (6) by reacting the octafluorotricyclodecane derivative (an alcohol compound) represented by the general formula (4) with a carboxylic acid represented by the general formula (5), R3COOH. For example, it is possible to react this alcohol compound with this carboxylic acid (e.g., acrylic or methacrylic acid) in the presence of an acid catalyst (e.g., sulfuric acid) at a temperature of 20-120° C., thereby producing the target product (e.g., an acrylic or methacrylic ester).
- In addition to the first to third processes, it is possible to react the octafluorotricyclodecane derivative (an alcohol compound) represented by the general formula (4) with a halide represented by the general formula (10), thereby producing the octafluorotricyclodecane derivative (a vinyl ether compound) represented by the general formula (11),
- R3−X (10)
-
- where R3 is defined as in the general formula (1). For example, the reaction can be conducted in a solvent in the presence of a base at a temperature of 0-100° C. for about 3-48 hr. This solvent is not particularly limited so long as it is inert in the reaction. Its examples are ethers (e.g., tetrahydrofuran and diethyl ether), hydrocarbons (e.g., toluene and xylene), and dimethylformamide. The base can be selected from organic and inorganic bases such as triethylamine and sodium hydride. Alternatively, the vinyl ether compound can also be synthesized by reacting the alcohol compound represented by the general formula (4) with acetylene in the presence of a catalyst (e.g., an alkali metal oxide) at a temperature of 100-200° C. Furthermore, the target octafluorotricyclodecane derivative (an allyl ether) can be synthesized by reacting the alcohol compound represented by the general formula (4) with an allyl chloride at a temperature of 100-200° C.
- Each target product obtained by the above-mentioned processes may be subjected to a conventional purification (e.g., concentration, distillation, extraction, recrystallization, filtration and column chromatography). It is possible to combine at least two of these.
- The following nonlimitative examples are illustrative of the present invention.

Then, the reaction tube was cooled with ice, followed by decreasing the inside pressure. After that, the contents of the reaction tube were put into a 2-liter round-bottom flask, followed by vacuum distillation. With this, 193 g (0.694 mol, yield: 62.0% (standard: cyclopentadiene)) of a distillate of 52-55° C./12 mmHg were collected. The identification of the obtained compounds were conducted by nuclear magnetic resonance analysis (1H, 13C, 19F) and infrared spectroscopic analysis. The results of these analyses are as follows.
