Proton-ligand and metal (Cu2+, Ni2+, Zn2+, Be2+) complex stability constants were determined for the β-keto esters Et-, Et-2-Me-, Et-2-Et-, Et-2-Pr-, Et-2-iso-Pr-, and Et-2-Bu-acetoacetate by pH titration in 50 volume % aqueous dioxane at 30° and ionic strength 0.2. The inductive and steric effects of the alkyl substituents result in a decreased stability of the metal complexes compared to the β-diketone complexes.
Journal of the Indian Chemical Society published new progress about 14284-06-1. 14284-06-1 belongs to copper-catalyst, auxiliary class Copper, name is Copper(II) ethylacetoacetate, and the molecular formula is 0, Quality Control of 14284-06-1.
