Margerum, Dale

DR. DALE MARGERUM (Purdue University) You need to be careful because you may not obtain a true Bronsted plot from what you have just described. You don t want to make a plot where each system has a different rearrangement. You want to be certain to have a common type of acid or base with which you are reacting. The literature is full of inverse Bronsted relationships in which there has been a poor choice of reaction acid-base pairs. Much confusion has been generated as a result. 

Dale Margerum Ralph Wilkins has mentioned the interesting effect of terpyridine on the subsequent substitution reaction of the nickel complex. I would like to discuss this point—namely the effect of coordination of other ligands on the rate of substitution of the remaining coordinated water. However, before proceeding we should first focus attention on the main point of this paper-which is that a tremendous amount of kinetic data for the rate of formation of all kinds of metal complexes can be correlated with the rate of water substitution of the simple aquo metal ion. This also means that dissociation rate constants of metal complexes can be predicted from the stability constants of the complexes and the rate constant of water exchange. The data from the paper are so convincing that we can proceed to other points of discussion.
