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 p1 R and R.sup.1 are hydrogen or alkyl having from 1 to 6 carbon atoms, 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 having from 1 to 6 carbon atoms, and the acid addition salts thereof, are new. These new compounds are also subject of the present invention.
本发明涉及一种制备公式(I)的
氨基二芳基亚砜衍
生物的新工艺,其中X为卤素,具有1至6个碳原子的烷氧基或基团--(N,R,R1),其中p1 R和R1均为氢或具有1至6个碳原子的烷基,R2为氢、卤素、具有1至6个碳原子的烷基、具有1至6个碳原子的烷氧基或苯基或苯
硫基,两者都可以选择地被一个或多个相同或不同的卤素和/或
氨基替代,以及它们的酸加成盐。公式(I)化合物具有药理活性,特别是具有强效驱虫剂作用,或可用作
杀虫剂组分的活性成分。因此,本发明涉及含有公式(I)化合物或其盐作为活性成分的药物和
杀虫剂组合物。公式(I)化合物中,如果取代基如上所定义,但X代表与亚砜基相对的邻位上的基团--N(R,R1),其中R和R1均代表氢,且R2不是氢、卤素、具有1至6个碳原子的烷基和具有1至6个碳原子的烷氧基,则其酸加成盐为新化合物。这些新化合物也是本发明的对象。
