Non-symmetrical tetraaza macrocyclic complexes of nickel(II) and their binding to synthetic polymer supports
摘要:
The synthesis and characterisation of a family of new tetraaza macrocyclic complexes of nickel(II) have been performed, via reaction of a nucleophilic macrocycle with various acid chlorides, or via peripheral functionalisation of suitable macrocycles. The new complexes have an asymmetric distribution of the peripheral groups on the macrocyclic rings and this is reflected in the appearance of their NMR spectra. Some of the new complexes have been incorporated into the structure of synthetic polymers, either via copolymerisation with a chosen comonomer, in this case styrene, or via reaction with a suitably functionalised, preformed polymer.

3-(ethoxymethylene)-2,4-pentanedione. This ligand and its copper(II) and nickel(II) complexes display two carbonylgroups which, according to various physical probes, are very different; one is strongly affected by a COCH 3 substituent while the other (which is far remote from this substituent) is almost unaffected. However, both groups are amenable to condensation with ethylenediamine to yield a new
