Participants

Reaction Steps

1-[bis(isodecyloxycarbonyl)methyl]-1,2,4-triazole, which is the product of Example 12 (15.6 g), 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.
