详细
The complexation of 3-substituted-2-(aryl-,methyl)sulfonylamino-4,5,6,7-tetrahydrobenzo[ b]thiophenes with Cu(II), Co(II), and Ni(II) ions in ammonia media was studied. Different types of complexes with Cu(II) ions were found depending on pH: with a ratio of 1: 2 at pH of ~4–5 and 1: 1 at pH of ~ 8–10. For the Co(II) and Ni(II) ions, the formation of 1: 1 complexes at pH of ~9–10 was established. The Cu(II), Co(II), and Ni(II) complexes [Cu(HL)2. 2H2O] and [ML. 2H2O] were separated and identified, and their solubility products were calculated. The effect of the nature of the functional group in the third position of the thiophene ring on the properties of the complexes of reagents with nonferrous metal ions was shown.
