This monograph consists of the proceedings of the Fifth International Symposium on the Activation of Dioxygen and Homogeneous Catalytic Oxidation, held in College Station, Texas, March 14-19, 1993. It contains an introductory chapter authored by Professors D. H. R. Barton and D. T. Sawyer, and twenty-nine chapters describing presentations by the plenary lecturers and invited speakers. One of the invited speakers, who could not submit a manuscript for reasons beyond his control, is represented by an abstract of his lecture. Also included are abstracts of forty-seven posters contributed by participants in the symposium. Readers who may wish to know more about the subjects presented in abstract form are invited to communicate directly with the authors of the abstracts. This is the fifth international symposium that has been held on this subject. The first was hosted by the CNRS, May 21-29, 1979, in Bendor, France (on the Island of Bandol). The second meeting was organized as a NATO workshop in Padova, Italy, June 24-27, 1984. This was followed by a meeting in Tsukuba, Japan, July 12-16, 1987. The fourth symposium was held at Balatonfured, Hungary, September 10-14, 1990. The sixth meeting is scheduled to take place in Delft, The Netherlands (late Spring, 1996); the organizer and host will be Professor R. A. Sheldon.

This series, Mechanisms of Inorganic and Organometallic Reactions, provides an ongoing critical review of the published literature concerned with the mechanisms of reactions of inorganic and organometallic compounds. Emphasis is on reactions in solution, although solid state and gas phase studies are included where they provide mechanistic insight. The sixth volume deals with papers published during the period January 1987 through June 1988 inclusive, together with some earlier work where it is appropriate to make comparisons. Coverage spans the whole area as comprehensively as practically possible, and the cited references are chosen for their relevance to the elucidation of reaction mechanisms. The now familiar format of earlier volumes has been maintained to facilitate tracing progress in a particular topic over several volumes, but some small changes have been made. Reflecting the a'mount of mechanistic work associated with ligand reactivity, and the growing importance of this area, Chapter 12 has been renamed and enlarged to bring together informa tion on both coordination and organometallic systems involving ligand reactions. Numerical data are usually reported in the units used by the original authors, except when making comparisons and conversion to common units is necessary.

First multi-year cumulation covers six years: 1965-70.
