An aromatic compound represented by the general formula ArX is reacted with a palladium compound and a phosphine derivative, in the presence of a first basic substance, thereby producing a palladium-complex compound represented by the general formula Ar&#x2014;PdLX. This palladium-complex compound is reacted with a benzoic acid represented by the general formula Ar&#x2014;COOH, in the presence of a second basic substance, thereby producing another palladium-complex compound represented by the following general formula.The above palladium-complex compounds are useful as catalysts and can be produced easily by the above reactions. In the above general formulas, Aris an aryl group; and X is a halogen that is fluorine, chlorine, bromine or iodine, trifluoromethanesulfonate group, an alkylsulfonate group having a carbon atom number of 1-4, or a substituted or unsubstituted arylsulfonate group; each L is independently a phosphine ligand; and Aris an aryl group.

A method of producing benzamides represented by the following general formula (1):

Method of producing benzamides

The invention relates to a method for producing a benzoic acid derivative represented by the general formula (1). The method includes the step of reacting an aromatic compound represented by the general formula (2), with carbon monoxide and a hydroxy compound (i.e., water or an alcohol), in the presence of (a) a metal compound containing a metal of 8, 9 and 10 groups of periodic table, (b) a first phosphine derivative represented by the general formula (R,),P&mdash;Q&mdash;P(R,),, and (c) a base,

Method for producing benzoic acid derivatives

The invention relates to a method for producing a bis(trifluoromethyl)benzene. This method includes the steps of (a) chlorinating a compound represented by the general formula (1) by chlorine, thereby to produce a trichloromethyltrifluoromethylbenzene; and (b) fluorinating the tricbloromethyltrifluoromethylbenzene by hydrogen fluoride, thereby to produce the bis(trifluoromethyl)benzene, ##STR1## where m is 1, 2 or 3. It is not necessary in the invention to handle solid in any reaction step. Therefore, the invention is very useful in the production of a bis(trifluoromethyl)benzene in an industrial scale
