[0027] Following compounds are illustrated as a concrete example of bis(diphenylvinyl)arene compound (1) of the present invention.

XBr, ClAr

a: The olefin portion may be cis or trans.

[0028] Although the method for preparing the compound of general formula (1) of the present invention is not especially limited, compound (E) which is an example of the compound of general formula (1), can be produced, for example as shown by the following figure:

[0029] by reacting a dihalomethyl aryl compound (A) with phosphorous ester (B) to produce a bis(dialkylphosphonomethyl)aryl compound (C) (step 1):

[0030] and by reacting the bis (dialkylphosphonomethyl)aryl compound (C) produced in step 1 with a benzophenone compound (D) (step 2).

[0031] In step 1, Ar of dihalomethylaryl compound (A) is the same as exemplified about the compounds of the above formula (1). Y is a halogen atom. As halogen atoms, for example, chlorine atom, bromine atom, and iodine atom are exemplified, and bromine atom is preferable.

[0032] In step 1, as the phosphorous ester (B), trimethyl phosphite, triethyl phosphate, tri-n-propyl phosphite, etc. are exemplified, and triethyl phosphite is preferable. Step 1 is usually carried out with using phosphorous ester (B) as a solvent.

[0033] In step 1, a solvent may be mixed further. As the solvent to be mixed, for example: ether solvents such as diethyl ether, tetrahydrofuran, tertiary butylmethylether, and dioxane; hydrocarbon solvents such as hexane, cyclohexane, toluene, xylene, etc. can be used as an inert solvent under the reaction. The amount of the solvent used is not especially limited, but it is usually about 10 to 500 times to dihalomethylaryl compound (A) in a weight ratio.

[0034] When using a phosphorous ester as a solvent, the reaction temperature is usually a reflux temperature. When using other solvent with mixing, it can be made to react, if necessary at a pressurized condition, at the same temperature with the reflux temperature of the case using phosphorous ester as a solvent. Specifically, the reaction temperature is usually about from 50° C. to 250° C., and suitably from 110° C. to 180° C.

[0035] Although the reaction time is not limited especially, it is usually for about from 30 minutes to 100 hours. Usually, the time when substantially all of the raw material dihalomethylaryl compound (A) is consumed, is considered as the end of reaction,

[0036] After reaction, bis (dialkylphosphonomethyl) aryl compound (C) can be obtained by distilling off the remaining phosphorous ester and solvent under reduced pressure. If necessary, from the resultant reaction concentrate, by a conventional method, for example, after mixing with a weakly basic water, such as sodium-hydrogencarbonate water etc., extraction with an organic solvent such as toluene, ethyl acetate, diethyl ether, dichloro methane, is carried out, and the desired bis (dialkylphosphonomethyl) aryl compound can be obtained by concentrating the resultant organic layer. Moreover, purification by column chromatography or distillation may be carried out according to needs.

[0037] In step 2, bis (dialkylphosphonomethyl) aryl compound (C) obtained by the above step 1 is reacted with benzophenone compound (D) under existence of abase, and compound (E) which is an example of bis (diphenyl vinyl) arene compound (1) of the present invention can be obtained.

[0038] By changing the benzophenone compound, various compounds of the present invention (1) can be produced.

[0039] The amounts of benzophenone compound (D) is usually about 0.5 to 10 mols, and preferably 1.5 to 4 mols based on 1 mol of bis (dialkylphosphonomethyl) aryl compound (C).

[0040] As the base used in step 2, exemplified are: inorganic bases such as sodium hydroxide, potassium hydroxide, etc.; alcoholate bases such as sodium methylate, potassium methylate, lithium methylate, sodium ethylate, potassium ethylate, lithium ethylate, sodium tertiary butyrate, potassium tertiary butyrate, lithium tertiary butyrate, etc.; and amide bases such as lithium amide, sodium amide potassium amide, etc. The amount of the base is not limited especially, it is usually about 1.5 to 10 mols, and suitably 2.5 to 4 mols based on 1 mol of the raw material of bis (dialkylphosphonomethyl) aryl compounds.

[0041] The reaction of step 2 is usually carried out in a solvent. As the solvent, an inert solvent is used, and exemplified are: halogenated solvents such as chloroform, dichloromethane, 1,2-dichloroethane, etc.; ether solvents such as ethyl ether, diethoxy methane, tetrahydrofuran, dimethoxy ethane, dioxane, etc.; and hydrocarbon solvents such as hexane, toluene, etc. Ether solvents are used preferably

[0042] The amount of the solvent used is not limited especially, but it is usually about 0.1 to 500 times to benzophenone compound (D) in a weight ratio.

[0043] The reaction temperature is not limited especially, but it is usually about 0 to 100° C. The reaction time is about 30 minutes to 24 hours. Disappearance of the raw material bis(dialkylphosphonomethyl)aryl compound is considered as the reaction end.

[0044] If necessary, from the resultant reaction mixture, by a conventional method, for example, after mixing with dilute sulfuric acid, extraction with an organic solvent such as toluene, ethyl acetate, diethyl ether, dichloro methane, is carried out, and the desired bis (diarylvinyl) aryl compound can be obtained by concentrating the resultant organic layer. Moreover, purification by column chromatography or distillation may be carried out according to needs.
