Abstract

The invention relates to a new process for the preparation of aminodiaryl sulfoxide derivatives of the formula (I), ##STR1## wherein X is halogen, alkoxy having from 1 to 6 carbon atoms or a group --(N,R,R.sup.1), in which PA1 R and R.sup.1 are hydrogen or alkyl having from 1 to 6 carbon atoms, PA0 R.sup.2 is hydrogen, halogen, alkyl having from 1 to 6 carbon atoms, alkoxy having from 1 to 6 carbon atoms or phenyl or phenylthio both optionally substituted by one or more identical or different halogen(s) and/or amino group(s), and acid addition salts thereof. The compounds of formula (I) are pharmaceutically active, in particular are potent anthelmintics, or can be used as active ingredients in pesticidal compositions. The invention therefore relates to pharmaceutical and pesticidal compositions containing compounds of formula (I) or salts thereof as active ingredient. Compounds of formula (I), in which the substituents are as defined above, but if X stands for a group --N(R,R.sup.1) in which R and R.sup.1 both represent hydrogen, and X is in para-position related to the sulfoxide group, then R.sup.2 is other than hydrogen, halogen, alkyl having from 1 to 6 carbon atoms and alkoxy h…
