For my first volume as Editor, I have invited Professor Colin D. Hubbard (University of Erlangen-Niirnberg, Erlangen, Germany and University of New Hampshire, Durham, NH, USA) as co-editor. Professor Hubbard studied chemistry at the University of Sheffield, and obtained his PhD with Ralph G. Wilkins. Following post-doctoral work at MIT, Cornell University and University of California in Berkeley, he joined the academic staff of the University of New Hampshire, Durham, where he became Professor of Chemistry in 1979. His interests cover the areas of high-pressure chemistry, electron transfer reactions, proton tunnelling and enzyme catalysis.

In organizing this conference, the editors were generously and actively assisted by many faculty and staff at Wayne State University and by many conference participants. We are particularly grateful for the assistance rendered by the other members of the organizing committee Ralph Wilkins, Norman Sutin, Richard Lindvedt, and Stanley Kirshner. Because so many were involved, a complete list of acknowledgments is impossible, but we wish to extend to all those who contributed so generously to the success of this conference our heartfelt thanks and appreciation. Finally, we acknowledge the financial support of the National Science Foundation, Dow Chemical Company, and Wayne State University.

DR. ENDICOTT In fact, the cobalt-eyelam-oxygen adduct can have a very short lifetime depending on the competition reactions. If the cobalt dioxygen adduct is generated in the presence of greater concentrations of CoAA([l4]aneN ), the intermediate lifetime is clearly shortened. The classical studies made by Ralph Wilkins, for instance, were carried out under conditions in which intermediates only achieved small stationary state concentrations.

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.
