Procedure
Example 9 is repeated, the 3,4,5-trichloroaniline being replaced by 2,4,5-trichloroaniline and 0.5 g of the same catalyst being introduced in place of 0.1 g. After a reaction time of 10 hours under the same conditions, 3-chloroaniline is obtained with a yield of 100% for a complete conversion of the 2,4,5-trichloroaniline and of the intermediates (2,5-, 2,3- and 3,4-dichloroanilines). The degree of hydrodechlorination of the solvent is 0.09%.
