Abstract
Abstract 1,4-Diamino-2,3,5,6-tetra(hydroxyimino)piperazine (DAPH4), 1-amino-4-(phenyl)-2,3,5,6-tetra(hydroxyimino)piperazine (PAPH4), 1-amino-4-(1-naphthyl)-2,3,5,6-tetra(hydroxyimino)piperazine (NAPH4) and 1-amino-4-(benzyl)-2,3,5,6-tetra(hydroxyimino)piperazine (BAPH4) were synthesized by the reaction of cyanogen di-N-oxide with substituted aminoglyoximes at −10°C. Their polymeric complexes with Ni(II), Cu(II) and Co(II) were prepared and characterized by 1H NMR, UV.-visible, IR and elemental analyses. Referee I: K. Moedritzer Referee II: P. R. Sharp
