In 1954, Curtis(46,47) discovered that tris (ethylenediamine)nickel(II) perchlorate would react with acetone to form three different yellow, diamagnetic perchlorate complexes containing ligands coordinated by amine and azomethine donor groups and Blight(19) extended this reaction to other 1,2-diamine complexes of copper(II) and nickel(II). The object of this work has been:- (i) The synthesis of polyamine complexes of nickel(II) and copper(II)(84). (ii) The investigation of the nature, structure(50) and chemical properties of the products obtained by reaction of some nickel(II) and copper(II) polyamine complexes with acetone(83,85,85). (iii) The extension of the reaction to other aliphatic carbonyl compounds, especially aldehydes.
