| الوصف: | Substitutions of 2,2'-biguinoline (biq) in Cu(biq) 2 + by 2,9-dimethylphenanthroline (dmp) and 1,10-phenanthroline (phen), in acetone, were found to be catalyzed by Lewis bases, L. The catalyzed pathway involves an intermediate mixed-ligand complex Cu(biq)L + , in which L is rapidly replaced by the incoming diimine ligand. The individual rate constants for L=iodide and acetonitrile were evaluated. Analysis of the respective rate constants, together with the equilibrium constants, clearly shows that the better nucleophile, iodide, is the more efficient catalyst |
