Trichloromethyl-substituted aromatic compounds are obtained by the chlorination of thioethers of the formula ##STR1## wherein Ar represents an optionally substituted aryl radial, X.sub.1 denotes hydrogen or halogen, and R.sup.1 represents optionally substituted alkyl, aralkyl, the nitrile group, an optionally substituted aryl radical or the group ##STR2## wherein Ar and X have the meaning given. The compounds, of which some are new, can be used as intermediate products for plant protection agents.
