STUDIES ON THE SYNTHESİS OF SOME NEW AMINOLYSED PRODUCTS: THEIR BIOLOGICAL ACTIVITY AND CHELATES

Interaction of 1,3-diaryl -2, 4- hexachlorocyclodiphosphazanes of the types (la-c) with some primary amines furnished the expected amino-derivatives. The elucidation of such aminoly- sed derivatives are essentially based on physical and Chemical evidence. Accordingly, structure (II) was suggested. The pKa, s of these compounds as well as their binary complexes with Co II, Ni II and Cu II in solution were studied spectrophotometrically and conductometrically. The determination of the micro amounts of these metals were also discussed.
