inversion reactions have been observed in nickel(II) complexes of macrocyclic tertiary tetra-amine ligands in which the nitrogen substituents are either 2-cyanoethyl or 2-carbamoylethyl; under certain conditions dealkylative loss of the cyanoethyl substituent occurs but loss of a carbamoyl substituent has not been observed for nickel(II) although it has for copper(II).
