Mixed Ligand Ni(II) Complexes of Isonitroso-β-Ketoimines, β-Ketoimines and Salicylaldimines and Some of Their Reactions; Importance of H-Bonding in the Stabilization of Isonitroso N-Bonded Isomer.

Abstract

A new series of diamagnetic nickel(II) complexes of isonitroso-β-
ketoimines,  β-ketoimines and salicylaldimines have been synthesised
and characterised by analytical, IR, NMR, CMR and
electronic spectral studies.  Synthesis of this type of complexes has
been achieved by chelate exchange method. The quasiaromatic character
of acetylacetoneimine moiety of mixed ligand complexes is
confirmed by conducting nitrosation, bromination and phenyl
isocyanation and the products have been characterised by elemental
analyses, electronic and IR studies.
