Abstract

"Process for obtaining sulfur compounds" of formula I Ar1-X-Ar2 I, wherein X means a thio radical, sulfinyl or a sulphonyl radical and each of the radicals Ar 1 and Ar 2 mean a monocyclic aryl radical substituted by an N-substituted amino-lower alkoxy radical, where the N-substituted amino radical is separated from the radical oxy at least 2 carbon atoms, their salts, N-oxides, salts of the N-oxides and quaternary ammonium compounds, characterized in that in a compound of formula (See formula) where X has the above-indicated meaning and each radical Ar10 and Ar20 means a monocyclic aryl radical, which is substituted by a radical R0 transformable into an N-substituted amino-lower alkoxy radical, or salt thereof, the radical is converted to the N-substituted lower alkoxy amino radical, where the N-substituted amino radical is separated from the oxy radical by at least 2 carbon atoms and, if desired, in a compound obtained the radical X is transformed into another radical representing this residue and/or, if desired, in a compound obtained, where the nitrogen of the N-substituted amino-lower alkoxy substituent carries a hydrogen atom, this is replaced by an organic radical and/or, if desired, a salt obtained is transformed into the free compound or into another salt and/or, if desired, a compound obtained is transformed into an N-oxide or a quaternary ammonium derivative and/or, if desired, a free compound obtained or an N-oxide are transferred It is formed into a salt and/or if desired, a quaternary compound is transformed into another quaternary ammonium compound and/or, if desired, a mixture of isomers is separated into the different isomers.
