Abstract
1,10-Phenanthroline-2,9-dicarbaldehyde has been prepared by oxidation of 2,9-dimethyl-1,10-phenanthroline with selenium dioxide. The value of the dialdehyde in the synthesis of open-chain multidentate chelating agents has been examined and the function of the di(phenylhydrazone) derivative is described. Steric constraints within the molecule render quadridentate function difficult and a distinct tendency to tridentate coordination is observed. Complexes of the dihydrazone with bivalent iron, cobalt, nickel and copper are described.
