Contributions from twenty-four international authorities in their field provide a leading-edge presentation of the most recent and in-demand applications of photochemical methodologies. Outlining a wide assortment of reaction types entailing cycloadditions, cyclizations, isomerizations, rearrangements and other organic syntheses, this reference offers unmatched coverage of all reactions in the foreground of organic chemistry such as stereoselectivity. This book also surveys reactions with photoinduced aromatic nucleophilic substitutions and illustrates photocycloadditions of alkenes to excited alkenes or carbonyls. Photochemists, organic and physical chemists, and graduate students in these disciplines would find that select experimental procedures demonstrate the industrial and academic value of reactions presented in this text.
