Synthesis of bis(amino alcohol)oxalamides and their usage for the preconcentration of trace metals by cloud point extraction.
C(2)-Symmetric two bis(amino alcohol)oxalamides (diamidediols) were synthesized and fully characterized. A new method was developed and successfully applied for the simultaneous preconcentration of both trace and toxic metals in water, by using C(2)-symmetric compounds. Under the optimum experimental conditions (i.e. pH = 10.0 +/- 0.2, 2.75 x 10(-3) mol L(-1) N,N'-bis[(1R)-1-ethyl-2-hydroxyethy...

The reaction of 1,2-bis-{2-[(2-hydroxy-ethyl)amino-methyl]-phen-oxy}ethane and fumaric acid in a mixed solution in ethanol-water (1:1 v/v) yields the title compound, C(20)H(30)N(2)O(4) (2+)·C(4)H(2)O(4) (2-)·4H(2)O. In the crystal structure, the anions, cations and water mol-ecules are connected via O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network. The fumarate anion and the N,N'...

In the hydrogen-bonding networks of 8-hydroxy-5-hydroxymethyl-3,6-dioxatricyclo[6.3.1.0(1.5)]dodecan-2-one and 5,7-bis(hydroxymethyl)-3,6-dioxatricyclo[5.3.1.0(1.5)]undecan-2-one, both C11H16O5, layers and double strands, respectively, lead to the formation of chains connected by hydroxy-to-hydroxy contacts, where the hydroxymethyl group, present in both structures, acts as a donor. The seconda...
