In the absence of molecular oxygen, the reactions of ascorbic acid with certain transition metal ions, especially Fe(III), Cu(II), mercury(II) [Hg(II)], or Cr(VI), result in their reduction and oxidation of ascorbic acid to DHA, for example, 2Fe(III) + ascorbic acid [right arrow] 2Fe(II) + DHA + [2H.
Additionally, it is also known that metal-containing liquid crystals in the form of metal binuclear carboxylates can be readily formed from the simple interaction of long chain sodium carboxylates and simple transition metal salts such as copper sulfate (ref 14).
