PROCESS FOR PREPARING 2-CHLORO-4-NITRO-ALKYLBENZENE |
| abstract |
In the preparation of 2-chloro-4-nitro-alkylbenzene by reacting 4-nitro-alkylbenzene with elemental chlorine or chlorine-donating compounds in the presence of a liquid-phase Friedel-Crafts catalyst, particularly high selectivities with respect to the exclusively in the 2-position achieved chlorinated target compounds, if a dibenzo-fused sulfur heterocycle of the formula II having the meanings given in the description for R1 to R8, X and n is used as the co-catalyst. Formula II |
