Summarizes the status of science in such areas as phosphorus in biology, phosphorus reaction mechanisms, stereochemistry, photochemistry of phosphorus compounds, applications of state-of-the-art NMR spectroscopy for phosphorus compounds, phosphorus compounds in flame retardants, insecticides, and synthesis. Offers theoretical, academic, and industrial applications of phosphorus chemicals and includes chapters from leading academic and industrial phosphorus chemists in both the U.S. and Canada. Includes contributions from Arthur D. F. Toy and H. Harnisch, who provide rare insights into the field, from describing the circuitous paths scientists travel in developing industrial products to how basic phosphorus chemistry can be harnessed for the good of humankind.
