HIGH-PURITY (FLUOROALKYL)BENZENE DERIVATIVE AND PROCESS FOR PRODUCING THE SAME

Title:

HIGH-PURITY (FLUOROALKYL)BENZENE DERIVATIVE AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2003/093212

Kind Code:

A1

Abstract:

A process for producing a (fluoroalkyl)benzene derivative which comprises: a step in which the total content of transition metals in Groups 3 to 12 in an alkylbenzene derivative is regulated to 500 ppm or lower in terms of the amount of the atoms; a step in which the side-chain alkyl group of the alkylbenzene derivative purified is halogenated through a photohalogenation reaction to obtain a (haloalkyl)benzene derivative; and a step in which the (haloalkyl)benzene derivative is subjected to a halogen-fluorine exchange reaction with at least 10 mol of HF per mol of the derivative to obtain a (fluoroalkyl)benzene derivative. The (fluoroalkyl)benzene derivative produced by the process is reduced in the content of impurities such as residual halogens and residual metals. It is useful as an intermediate for functional chemicals for use in applications including medicines and electronic materials.
