Özet

The preparation of copper ascorbate in CH,Cl, is described. The reaction between copper(II) methoxide and L-ascorbic acid in the presence of N,N,N',N'-tetramethylethylenediamine (TMEDA) and under strictly anaerobic conditions leads to the formation of a stable Cu(Il)-ascorbate complex. No redox reaction takes place. Spectroscopic evidence suggest that the compound is polymeric where Cu(II) is chelated by the enolic oxygens of one ascorbate unit and the side chain alcoholic oxygens of another.
