実験手順

A solution of 4.6 g (34 mmol) of aluminum chloride and 4.6 g (34 mmol) of disulphur dichloride in 344 g (2.55 mol) of sulphuryl chloride was added dropwise to a mixture of 57.5 g (250 mmol) of p-chlorobenzotrichloride and 115 g (850 mmol) of sulphuryl chloride at 40° C. The reaction mixture was further processed in the manner described in Example 5, that is to say that, after the working up, unreacted p-chlorobenzotrichloride and 3,4-dichlorobenzotrichloride were separated off by distillation and fed to renewed chlorination with sulphuryl chloride under the conditions given here. By distillation of the combined sump fractions, 2,4,5-trichlorobenzotrichloride was obtained in a yield of 47% of theory.
