| Zusammenfassung: | In the process for the nuclear chlorination of alkylbenzenes, such as toluene, in the presence of a para-directing catalyst system comprising a substantially iron-free Lewis acid catalyst and thianthrene compound co-catalyst, wherein the reaction mixture is in contact with iron or an alloy thereof, the para-directing effect of the catalyst system is improved by the addition of an amide. |
