Abstract

The present invention relates to a process for the sulfinylation of a pyrazole derivative, characterized in that 5-amino-1-[2,6-dichloro-4-(trif1uoromcthyl)phenyl]-1H-pyrazole-3-carbonitrile (II) is reacted with a sulfinylating agent selected from trifluoromethylsulfinic acid, trifluoromethylsulfinic acid anhydride, and a trifluoromethylsulfinale alkaline or alkaline earth metal salt and mixtures of the acid and/or the salt(s), in the presence of at least one amino acid complex wherein the amine(s) are selected from tertiary amines and the acid(s) are selected from hydrofluoric, hydrochloric, hydrobromic and hydroiodic acid and sulfonic acid derivatives, and with the addition of a halogenating agent.
