1-[bis(isodecyloxycarbonyl)methyl]-1,2,4-triazole, which is the product of Example 12 (15.6g), was dissolved in carbon tetrachloride (20 ml). Phosphorus trichloride (3 drops) was added and the solution was stirred and heated at 60° whilst a slow stream of chlorine was bubbled through it for 1 hour. The solution was then cooled, washed with aqueous sodium sulphite solution and with water, and the solvent was distilled under reduced pressure yielding 1-[bis(isodecyloxycarbonyl)chloromethyl]-1,2,4-triazole (12.9 g), which had a purity of 82.4% as measured by non-aqueous titration with perchloric acid. This compound was evaluated as an extractant for copper by the procedure of Example 1 and the results are presented in Table 1.
