The present invention relates to a novel biphenyl compound, and particularly to a novel biphenyl compound in which two phenyl groups of biphenyl each have a different functional group. Biphenyl is a chemically stable compound, and it is known that polymers containing biphenyl groups are excellent in terms of heat resistance, chemical resistance, and the like. By the way, in order to introduce biphenyl groups into a polymer, it is first necessary to synthesize a compound in which highly reactive functional groups are introduced into each of the two phenyl groups of biphenyl. Biphenyl compounds having these functional groups can be used not only as raw materials for polymer synthesis, but also as biphenyl compounds with various substitution values, such as compounds with anti-inflammatory activity described in JP-A-50-25537. It is also important as a synthetic intermediate for pharmaceuticals, agricultural chemicals, and dyes. The present invention has been made in view of the current situation, and provides that a novel biphenyl compound represented by the following general formula can be used as a synthetic intermediate for pharmaceuticals, agricultural chemicals, dyes, etc., particularly as an intermediate for polymer production, or as a raw material. They found it useful and completed the present invention. The novel vinylphenyl compound of the present invention is represented by the following general formula. However, in the formula, when substituent R 1 is an acetoxy group,
The substituent R 2 is a 1-hydroxyethyl group or a vinyl group, and when the substituent R 1 is a hydroxyl group, the substituent R 2 is a 1-hydroxyethyl group or a vinyl group. Examples of the novel biphenyl compounds of the present invention and starting compounds therefor include the following. (1) Starting compound 4-acetoxy-4'-acetylbiphenyl (2) 4-acetoxy-4'-(1-hydroxyethyl)biphenyl (3) 4-acetoxy-4'-vinylbiphenyl (4) 4-hydroxy-4'-(1-hydroxyethyl)biphenyl (5) 4-hydroxy-4'-vinylbiphenyl The starting biphenyl compound () of the present invention can be obtained by rearranging 4-acetoxybiphenyl (B) obtained by acetylating 4-hydroxybiphenyl (A) in nitrobenzene using an aluminum chloride catalyst, or by rearranging 4-acetoxybiphenyl (B) obtained by acetylating 4-hydroxybiphenyl (A) using an aluminum chloride catalyst. 4-Hydroxy- obtained by rearrangement reaction in the absence of solvent as a catalyst
It is synthesized by acetylating 4'-acetylbiphenyl (C) with acetic anhydride. This starting biphenyl compound () or the above 4
-Hydroxy-4'-acetylbiphenyl (C) is reduced to obtain the novel biphenyl compound () of the present invention. As the reduction method, a method of reducing with hydrogen in the presence of a metal catalyst such as Pd or Ni, or a method of using a metal hydride such as sodium borohydride, lithium aluminum hydride, etc. can be adopted. When the obtained novel biphenyl compound ( ) is acetylated, for example, with acetic anhydride, the novel biphenyl compound ( ) of the present invention is obtained. Alternatively, if the starting biphenyl compound () is reduced using sodium borohydride, the new biphenyl compound () may be directly produced depending on the reduction conditions.
You can also get The obtained new biphenyl compounds () and () have two phenyl groups in biphenyl, a phenolic OH group and an alcoholic OH group in compound (), and an alcoholic OH group in compound ().
It is a compound that has functional groups with different reactivity such as OH group and acetoxy group, and it can be used as an intermediate in the production of heat-resistant and chemical-resistant polymers that utilize these differences in reactivity, and in the production of new agricultural chemicals and dyes. It is expected that it will be put to good use. Furthermore, the novel biphenyl compound (2) of the present invention is obtained by dehydration of this new biphenyl compound (2), and the novel biphenyl compound (2) of the present invention is obtained by acetylating this compound (2). On the other hand, when the above-mentioned novel biphenyl compound () is dehydrated, the new biphenyl compound ()
and Compound () are obtained, and when this equivalent mixture is hydrolyzed, Compound () is obtained. For the dehydration reaction, there is a method of heating to a high temperature in the presence of alumina and acidic potassium sulfate, but a large amount of side reaction products are produced, making it difficult to isolate the new biphenyl compound (), and the yield is low. Therefore, in the present invention, by adopting a method using zinc chloride and trichloroacetic acid, the yield could be improved. The novel biphenyl compound () obtained by the present invention has a polymerizable vinyl group in one phenyl group of biphenyl and a highly reactive phenolic OH group in the other phenyl group, so it is particularly functional. It can be used as a useful monomer in the production of polymeric compounds. Moreover, the novel biphenyl compound () of the present invention is
Since one phenyl group has an acetoxy group,
It is a compound with higher polymerization reactivity than compound (), and like compound (), it can be widely used in the production of functional polymer compounds. Hereinafter, the present invention will be explained in detail based on examples. Production Example 1 (Production of starting compound) Production of 4-hydroxy-4'-acetylbiphenyl (C). A mixture of 10 g of aluminum chloride and 2 g of common salt was placed in a flask equipped with a calcium chloride drying tube.
When heated to 180°C, the aluminum chloride melted into a homogeneous liquid. After cooling this to 140°C, 5 g of acetoxybiphenyl (B), melting point 81.0-82.0°C, was added, and while stirring, the mixture was heated again to 180°C and held for 3 minutes. After the reaction mixture was cooled to room temperature, it was poured into permanent water containing hydrochloric acid, 30 ml of methylene chloride was added, and the mixture was stirred. After separating the methylene chloride layer, washing with water and drying, hexane was added little by little to separate a yellowish brown oil.Meanwhile, the remaining solution was concentrated and the resulting solid was dissolved in acetone-hexane mixed solvent. Recrystallization yielded white crystals of 4-hydroxy-4'-acetylbiphenyl (C). Yield: 0.7g Melting point: 207.5-208.5°C Characteristic infrared absorption: OH structure: 3300cm -1 In addition, it was confirmed by liquid chromatography that it was a single component.
