Bartholornew Press, Dorking Foreword The volume of published work in organophosphorus chemistry has again increased, and several Reporters have had great difficulty in keeping within their allotted space. Much, but not all, of the research has been of a routine and predictable nature. The stimulus provided by the discovery of phosphonomycin is still being felt. It would be interesting to know just how many research projects and proposals have been linked, however tenuously, to this phosphorus-containing antibiotic. Six-co-ordinate species are being identified more frequentIy. Some are remarkably stable and have been isolated, whereas the intermediacy of others in reactions has been inferred from kinetic data. Clearly, much more will be heard of these. Finally, on the instrumental front, Fourier-transform 31Pn.m.r. spectroscopy is proving to be a very powerful tool for the detection and study of unstable intermediates, for example in Arbusov reactions, and one can look forward to the solution of many long-standing problems in organophosphorus chemistry using this technique. We hope to report on some of these in Volume 9. S.Trippett Contents Chapter 1 Phosphines and Phosphonium Salts By D, W.
