The present invention relates to a method for producing phenyl benzoate by reacting halobenzene, hydroxybenzene, and carbon monoxide in the presence of a platinum group catalyst and a base. Benzoic acid phenyl ester is useful as a raw material for heat-resistant polyesters, organic electronic materials, etc. Conventionally, benzoic acid phenyl ester is known to be obtained by the condensation reaction of benzoic acid and phenol, but this method requires a complex catalyst and an expensive dehydrating agent, which is not always satisfactory. No yield could be obtained. It is also known that benzoic acid chloride can be obtained by a condensation reaction of benzoic acid chloride and phenol, but it has been difficult to obtain benzoic acid chloride industrially advantageously. As a result of intensive research aimed at obtaining benzoic acid phenyl ester in an industrially advantageous manner, the present inventor discovered a new reaction and arrived at the present invention. That is, the present invention provides the general formula () (X in the formula represents a bromine atom or an iodine atom, R represents an alkyl group, an alkenyl group, an aryl group, a cycloalkyl group, an alkoxy group, a phenoxy group, an acyl group, an acyloxy group, a nitro group, a cyano group, a formyl group, represents a carbalkoxy group and a hydroxy group, and n represents 0 to 3), and a halobenzene represented by the general formula () (R and n in the formula have the same meanings as above) and carbon monoxide are combined into a group consisting of a simple platinum group metal or a complex of a salt of the platinum group metal and an organic ligand. General formula (), characterized in that the reaction is carried out in the coexistence of one type of platinum group catalyst selected from the following and a base: The present invention relates to a method for producing benzoic acid phenyl ester represented by the formula (R and n have the same meanings as above). Examples of the halobenzene represented by the general formula () used in the method of the present invention include bromobenzene, o-bromotoluene, p-methoxybromobenzene, p-phenoxybromobenzene, p-
Bromophenol, m-acetylbromobenzene, p-bromophenyl acetate, p-nitrobromobenzene, m-cyanobromobenzene, p-bromobenzaldehyde, iodobenzene, m-iodotoluene, p-methoxyiodobenzene, p-
Iodophenol, methyl p-bromobenzoate,
Examples include o-nitroiodobenzene, m-iodobenzaldehyde, and p-cyanoiodobenzene. Further, as the hydroxybenzene represented by the general formula (), for example, phenol, o-methoxyphenol, p-methoxyphenol, p-phenoxyphenol, hydroquinone, m-acetylphenol, resorcin monoacetate,
p-nitrophenol, p-cyanophenol,
Examples include p-hydroxybenzaldehyde and methyl p-hydroxybenzoate. The amount of hydroxybenzene used is preferably 0.1 to 10 times, particularly 0.3 to 3 times by mole, per mole of halobenzene. Furthermore, carbon monoxide may be a pure gas, but does not necessarily have to be of high purity, such as nitrogen gas,
A gas mixture diluted with an inert gas such as carbon dioxide may also be used. Normal pressure is sufficient for the pressure of carbon monoxide, but of course it may be pressurized, and usually 0.1 to 100 kg/cm 2 G is appropriate. As the platinum group catalyst used in the method of the present invention, (i)
Platinum group metals alone such as palladium, platinum, rhodium, ruthenium, iridium, osmium or (ii) platinum group metal salts such as acetates, nitrates, chlorides, bromides, etc. of these metals with organic ligands. Examples include complexes. The platinum group metal (i) can be used alone, but these metals can also be supported on a carrier such as activated carbon, graphite, silica gel, alumina, silica alumina, or molecular sieve. In addition, as a complex of a platinum group metal salt and an organic ligand (ii), for example, a platinum group metal salt such as palladium chloride, palladium bromide, rhodium chloride, or ruthenium bromide and triphenylphosphine, tri-o-tolylphosphine, etc. PdCl 2 (Pph 3 ) 2 which is a complex with yne, 1,2-bis(diphenylphosphino)ethane, tri-n-butylphosphine, triethylphosphine, benzonitrile, carbonyl, etc.
PdBr 2 (Pph 3 ) 2 , Pd (Pph 3 ) 4 , PdCl 2 (phCN) 2 ,
Pd(CO)( Pph3 ) 3 , RhCl( Pph3 ) 3 , RhCl(CO)
(Pph 3 ) 2 , Pt(CO) 2 (Pph 3 ) 2 (where ph represents a phenyl group), etc. In some cases, the organic ligand may be added in an excess amount to form a complex with the platinum group metal salt. The amount of platinum group catalyst used is based on the reaction medium.
0.01-10% by weight, especially 0.05-2% by weight is preferred. In addition, bases used with platinum group catalysts include triethylamine, tri-n-butylamine,
Amines such as pyridine, dimethylaniline, and tetramethylurea, alkali metal and alkaline earth metal salts of phenols, organic carboxylic acids such as sodium acetate and potassium propionate, sodium carbonate, potassium carbonate, sodium hydrogen carbonate, Examples include inorganic bases such as calcium oxide, sodium hydroxide, potassium hydroxide, and calcium hydroxide. The amount of such a base to be used is preferably 0.1 to 10 times, particularly 0.3 to 3 times by mole, per mole of halobenzene. This reaction is carried out without a solvent or in a solvent. As a solvent, ethers such as diethyl ether, diethylene glycol diethyl ether, and tetrahydrofuran, aromatic hydrocarbons such as benzene, toluene, xylene, nitrobenzene, and chlorobenzene, nitriles such as acetonitrile and benzonitrile, and others such as N, N- dimethylformamide, N,N-dimethylacetamide,
Dimethyl sulfoxide, N-methylpyrrolidone,
Examples include hexamethylphosphoramide. The reaction temperature is preferably room temperature to 250°C, particularly 50 to 160°C. This reaction proceeds satisfactorily under extremely mild reaction conditions of room temperature and pressure. Of course, maintaining the reaction under high temperature and high pressure allows the reaction to proceed more effectively. The benzoic acid phenyl ester obtained by the method of the present invention is a compound represented by the above general formula (), and representative examples thereof include phenyl benzoate, p-hydroxybenzoic acid phenyl, and p-methoxybenzoic acid phenyl ester. -Methoxyphenyl, p-hydroxybenzoic acid o-cresyl, p-methoxybenzoic acid phenyl, p-hydroxybenzoic acid p-hydroxyphenyl, p-hydroxybenzoic acid m-acetylphenyl, p-acetoxybenzoic acid p- Carbomethoxyphenyl, o-methylbenzoic acid p-
Examples include nitrophenyl, p-cyanophenyl p-cyanobenzoate, phenyl p-nitrobenzoate, and the like. Examples 1 to 7 A rotary stirring type stainless steel autoclave with an internal volume of 100 ml was filled with predetermined amounts of halobenzene, hydroxybenzene, a platinum group catalyst, a base, and optionally a solvent, and after sealing, carbon monoxide was added to the autoclave for 20 minutes.
The mixture was charged under pressure and kept at 100°C to react for 1.5 to 5 hours to obtain benzoic acid phenyl ester. Incidentally, almost no by-products were observed. The results are shown in Table 1.
