Complexation of copper(II) with 2′,2′-dialkyl-para-tert-butylbenzohydrazides

The complexation of copper(II) with 2′,2′-dimethyl-, 2′,2′-dibutyl-, and 2′,2′-diisobutyl- para - tert -butylbenzohydrazide in water-ethanol media was studied. The reagents (HL) formed [Cu(HL)] 2+ and [Cu(HL) 2 ] 2+ cationic complexes in a weakly acidic medium and uncharged CuL 2 complexes in an alk...

Description
Summary:The complexation of copper(II) with 2′,2′-dimethyl-, 2′,2′-dibutyl-, and 2′,2′-diisobutyl- para - tert -butylbenzohydrazide in water-ethanol media was studied. The reagents (HL) formed [Cu(HL)] 2+ and [Cu(HL) 2 ] 2+ cationic complexes in a weakly acidic medium and uncharged CuL 2 complexes in an alkaline medium. log K st was calculated for these complexes. The effect of 2′,2′-alkyl radicals on the stability of the complexes was considered. The obtained results were compared with data on the complexation of copper(II) ions with 2′,2′-dialkylbenzohydrazides.
