, (2008/06/13)
A process for producing a halogen-containing ethylbenzene derivative represented by the general formula: STR1 where X is a halogen atom, and W is a nitrile group, a carboxyl group, a lower alkoxycarbonyl group or an amidocarbonyl group, which comprises diazotizing aniline with a nitrite in a solution mixture comprising a hydrophilic organic solvent, an aqueous mineral acid solution and a vinyl compound represented by the general formula: where W is as defined above, to form a benzenediazonium salt, and reacting the benzenediazonium salt, without isolating it from the reaction system, with said vinyl compound in the presence of halogen ions and a copper compound as a catalyst.
