Metal-mediated addition of alcohols to dicyandiamide

The syntheses of 1-amidino-O-alkylurea sulphates and their corresponding copper(II) and nickel(II) complexes are described. These compounds exhibit bi-univalent electrolyte conductances in aqueous solution. The electronic spectra and magnetic moments of the copper(II) and nickel(II) complexes are characteristic of square planar stereochemistry. Vibrational spectra provide useful information regarding ligand bonding sites.
