| abstract | a) mit einer wässrigen Lösung, Suspension oder Emulsion von Ammoniak, Hydrazin, eines primären oder sekundären aliphatischen Amins oder aromatischen Amins der Benzolreihe bei 0 bis 100°C zu den entsprechenden 4-Chlorbenzolsulfonamiden, oder b) mit einer wässrigen Alkalimetallsulfitlösung bei 20 bis 90°C bei pH 6 bis 9 zu den entsprechenden 4-Chlorbenzolsulfinaten und daraus durch Neutralisieren der Lösung mittels Säure zu der freien 4-Chlorbenzolsulfinsäure oder durch Umsetzen mit Alkylierungsmitteln zu den entsprechenden 4-Chlorphenylalkylsulfonen, oder c) mit der mindestens stöchiometrischen Menge eines Alkanols bei 20 bis 90°C zu den entsprechenden 4-Chlorbenzolsulfonsäurealkylestern. Process for the preparation of 4-chlorophenylsulfonyl compounds of the general formula (1) wherein R represents a hydrogen or chlorine atom or an alkyl, oxalkyl, alkoxy or hydrazino group, a primary amino group, primary or secondary alkylamino group, aralkylamino group or phenylamino group, where the phenyl group may be substituted, or a 4-chlorophenyl group by: 1 mole of chlorobenzene with a mixture of 1 mole of chlorosulfonic acid and 1 mole of thionyl chloride at 20 to 90 ° C with the proviso that the reaction mixture is always liquid, and the resulting 4-chlorobenzenesulfochloride in the form of a melt directly or after separation from that as By-product obtained 4,4'-dichlorophenyl sulfone a) with an aqueous solution, suspension or emulsion of ammonia, hydrazine, a primary or secondary aliphatic amine or aromatic amine of the benzene series at 0 to 100 ° C to the corresponding 4-chlorobenzenesulfonamides, or b) with an aqueous alkali metal sulfite solution at 20 to 90 ° C at pH 6 to 9 to the corresponding 4-chlorobenzenesulfinates and therefrom by neutralizing the solution with acid to the free 4-chlorobenzenesulfinic acid or by reaction with alkylating agents to give the corresponding 4-chlorophenylalkyl sulfones, or c) with the at least stoichiometric amount of an alkanol at 20 to 90 ° C to the corresponding 4-chlorobenzenesulfonic acid alkyl esters. |
