Definitions
- the present invention relates to a method for producing adamantane dihalide useful as a raw material for producing a functional material or an electronic material.
- Adamantane derivatives are expected to be used as raw materials for the production of high-functional materials such as heat-resistant polymer materials and electronic materials such as resists for semiconductors because of their characteristics of high heat resistance and high transparency.
- dihalogenated adamantane is important as a raw material for synthesizing various adamantane derivatives having two functional groups.
- adamantane halide produced by these methods is usually a mixture of a monohalide, a dihalide, and a trioctalogenate.
- the main product of this mixture is usually adamantane monohalide, and the yield of dihalogenated adamantane is low.
- the yield of 1,3-dichloroadamantane is 80% or less. It is.
- the present inventors have conducted intensive studies to solve the above-mentioned problems. As a result, they have found that the above problems can be solved by reacting adamantane with halosulfonic acid under specific temperature conditions, and have completed the present invention.
- an object of the present invention is to provide a method for producing a high-purity dihalogenated adamantane in high yield under mild conditions without using metals and metal salts.
- the present invention relates to a method for producing a dihalogenated adamantane by reacting adamantane, which may be substituted at the 1-position with an alkyl group, with halosulfonic acid, at a temperature of 15 to 15 ° C. in the first stage.
- a method for producing a dihalogenated adamantane comprising performing a monohalogenation reaction, and then performing a second stage dihalogenation reaction at a temperature of 17 to 35 ° C.
- adamantane as a reaction raw material is generally unsubstituted, but may be substituted at the 1-position with an alkyl group.
- an alkyl group a linear alkyl group having 1 to 4 carbon atoms such as a methyl group, an ethyl group, and a propyl group is preferable, and a methyl group is more preferable.
- the halosulfonic acid used in the present invention is
- halogen include fluorine, chlorine, bromine, and iodine.
- halosulfonic acid include chlorosulfonic acid, bromosulfonic acid, and sulfonic acid. From the viewpoint of availability, chlorosulfonic acid is particularly preferred.
- the above 1-position may be substituted with an alkyl group.
- Reaction of damantane (hereinafter also simply referred to as adamantanes) with halosulfonic acid gives dihalogenated adamantane.
- the main product of the synthesized dihalogenated adamantane is a 1,3-dihalogenated adamantane represented by the following formula (1).
- the synthesized dihalogenated adamantane is mainly an alkyl-1,3,5-dihalogenated adamantine represented by the following formula (2).
- R represents a linear alkyl group having 1 to 4 carbon atoms.
- the ratio of adamantanes and halosulfonic acid charged is not particularly limited. However, if the proportion of octasulfonic acid is extremely small, the reaction does not proceed sufficiently. Therefore, the proportion of the halosulfonic acid to be added is preferably at least twice the molar amount with respect to the adamanone.
- the proportion of halosulfonic acid used is set to adamantane so that the halosulfonic acid functions sufficiently as a reaction solvent and further improves the yield.
- the amount is 5 to 15 times, most preferably 8 to 12 times, the molar amount of the compound.
- the method for mixing the adamantane with the halosulfonic acid is not particularly limited. Usually, a method of dropping halosulfonic acid into adamantane or an organic solvent solution thereof is preferable.
- the most important feature of the present invention is that, when reacting the adamantane with the halosulfonic acid, first, the first-stage monohalogenation reaction is carried out at a temperature of —5 to 15 ° C. The second stage dihalogenation reaction is performed at a temperature of 35 ° C. By performing such a two-step reaction at different characteristic reaction temperatures, the amount of by-products such as trihalogenated adamantane can be suppressed to a small level, and the desired dihalogenated adamantane can be obtained more selectively. become.
- adamantane is first monohalogenated (hereinafter, this reaction is also referred to as monohalogenation reaction).
- octalogenation proceeds to generate a dihalide (hereinafter, this reaction is also referred to as a dihalogenation reaction), and further proceeds to further generate a trihalide and a tetrahalide.
- this reaction when the reaction temperature is maintained at 15 to 15 ° C., the monohalogenation reaction proceeds.
- monohalogenation reaction starts to proceed actively when the reaction temperature exceeds 17 t.
- reaction temperature When the reaction temperature is increased to 17 ° C. or higher from the beginning of the reaction, the reaction proceeds rapidly from the beginning of the reaction to generate a dihalide, and the halogenation reaction proceeds at a stretch until the formation of a trihalogenated product. It will be in an easy state. Therefore, under such temperature conditions, the production amount of the trihalide increases, and the yield of the dihalogenated adamantane decreases.
- the first stage reaction temperature is more preferably 5 to 15 ° C.
- the first-stage reaction temperature is lower than -5 ° C, the monohalogenation reaction hardly proceeds.
- the liquid temperature is preferably kept at 5 ° C. or lower so that the reaction does not run away.
- the first-stage monohalogenation reaction is carried out until most of the charged adamantane is monohalogenated.
- the reaction time is generally 30 minutes or more, preferably 1 hour to 3 hours.
- the reaction temperature in the second stage is preferably from 17 to 25 ° C from the viewpoint of obtaining a dihalogenated adamantane at a particularly high yield.
- the reaction temperature in the second step is higher than 35, the trihalogenation reaction of the dihalogenated adamantane proceeds actively.
- This second-stage reaction needs to be performed until the dihalogenation reaction sufficiently proceeds.
- the reaction time is preferably from 1 hour to 24 hours, and more preferably from 3 hours to 8 hours.
- the reaction temperature may be changed to a plurality of temperatures within the specified reaction temperature range.
- the reaction pressure in each reaction step is not particularly limited, but normal pressure is generally used.
- the above two-step reaction can be carried out either in the presence or absence of an organic solvent. However, it is particularly preferred to work in the absence of an organic solvent. In this case, the halosulfonic acid acts as a solvent.
- the solubility of adamantane dihalogenated adamantane in halosulfonic acid is extremely low.
- the solubility of monohalogenated adamantane in halosulfonic acid is large.
- Halosulfonic acid exhibits such a unique solubility property. Therefore, when the halosulfonic acid as a reaction reagent is used as a reaction solvent without using an organic solvent, the above-mentioned specific solubility property of the halosulfonic acid can be effectively used. As a result, as described below, it is possible to selectively obtain a dihalogenated adamantane with high purity.
- the reaction solution when adamantanes and halosulfonic acid are charged, the reaction solution is initially in a suspended state in which adamantanes are suspended. As the time elapses, the first-stage reaction proceeds to produce monohalogenated adamantane, the product dissolves well in halosulfonic acid, and the reaction solution changes to a transparent homogeneous solution. . Next, the resulting monohalogenated adamantane is further chlorinated in a solution of halosulfonic acid and smoothly transformed into a dihalide. However, most of the generated adamantane dihalide precipitates due to its extremely low solubility in halosulfonic acid as described above. . As a result, the reaction solution returns to a suspended state.
- the reactivity between the dihalogenated adamantane and the halosulfonic acid is significantly reduced.
- the amount of by-produced trihalogenated adamantane in the second-stage reaction can be greatly reduced.
- the reaction solution changes from a suspended state to a homogeneous solution. From this change, the end of the first-stage reaction can be easily confirmed visually. As a result, the first-stage reaction proceeds to the second-stage reaction in an insufficient state, increasing the amount of trihalogenated adamantane produced or performing the first-stage reaction longer than necessary. Such inconvenience can be prevented.
- the formation of the resulting dihalogenated adamantan in the reaction solution makes the isolation of the target product extremely advantageous. That is, when a crude product of a dihalogenated adamantane is obtained by, for example, reacting an adamantane with a halosulfonic acid, the physicochemical properties of the target product dihalogenated adamantane are similar to those of the dihalogenated adamantane according to a conventional method. In general, the separation from the monohalogenated adamantane is performed by a complicated purification means such as chromatography.
- the filtration is preferably performed under a nitrogen atmosphere. If the temperature of the reaction solution during filtration exceeds the upper limit of the reaction temperature range of the second stage, the reaction of adamantane dihalide to adamantane trihalide may proceed. . There is also concern that the solubility of the dihalogenated adamantane will increase and the yield will decrease. Therefore, it is preferable to perform filtration within the range of the reaction temperature of the second stage.
- the thus obtained precipitate of dihalogenated adamantane may be further purified to high purity by washing with water, solvent extraction, crystallization and the like, if necessary.
- any organic solvent may be used without limitation as long as it has no reactivity with octarosulfonate.
- chlorinated solvents such as dichloromethane and 1,2-dichloroethane are preferred.
- the amount of the organic solvent used is not particularly limited, but is an amount that can sufficiently dissolve the reactants and does not significantly reduce the yield of the kettle. Specifically, the amount is preferably 5 to 20 times the weight of the adamantane.
- the resulting dihalogenated adamantane is usually dissolved in the reaction solution at the end of the second-stage reaction.
- a method for isolating dioctogenated adamantane from the reaction solution first, ice water is added to the reaction solution to decompose the halosulfonic acid, and then water and an organic solvent layer containing a dihalogenated adamantane are separated. Thereafter, the organic solvent layer is washed with water, then the solvent is distilled off, dried and crystallized.
- the equipment used in the above reaction has a structure that cuts off contact with the atmosphere. This structure prevents the halosulfonic acid from reacting with water and decomposing to generate acid gas.
- the inside of the equipment Prior to the reaction, the inside of the equipment should be thoroughly dried with an inert gas such as nitrogen and dried in advance. During the reaction, it is preferable that the reaction is sealed or that an inert gas such as nitrogen is continuously ventilated.
- an inert gas such as nitrogen is continuously ventilated.
- a high-purity and high-purity dihalogenated adamantine can be produced under mild conditions with high yield. When no solvent is used during the reaction, the difference in solubility of adamantan dihalide and monohalogen adamantane in halosulfonic acid is utilized to easily isolate adamantan dihalide in good yield. Can be purified.
- the dihalogenated adamantane obtained by the method of the present invention can be derived into adamantanediol by hydrolysis or the like, or can be converted into a diaminoadamantane by ammonolysis or the like to obtain a functional material such as a heat-resistant polymer or the like. It can be used effectively as a raw material for electronic materials such as resists.

- Example 2 The same operation as in Example 1 was carried out, and chlorosulfonic acid was added dropwise to 5.0 g (0.037 mol) of adamantane at 10 ° C., followed by a reaction for 2 hours. The reaction solution became a clear homogeneous solution. Next, the temperature of the reaction solution was raised to 40 ° C., and the reaction was carried out for 5 hours.
