Abstract

The copper(II) alkoxide, bis(2-(2-ethoxyethoxy)ethoxide)copper(II), was prepared and had a solubility in organic solvents greatly exceeding those of simple copper(II) alkoxides (>0.4 mol/L in toluene at room temperature). Copper 2-(2-ethoxyethoxy)ethoxide (2-(2-ethoxyethoxy)ethoxide = 2,2-EEE) toluene or toluene/THF solutions gelled upon exposure to moisture. These solutions were hydrolysed with 0.2, 1.0, 2.0, 4.0, and 20.0 equivalents of H2O and the resulting powders were characterized by IR spectroscopy and SEM.
