Embarking on a new millennium, the book in hands describes the recent developments of organsoselenium chemistry in all facets. Various distinguished scientists have contributed, with their skill and expertise, making this book a valuable source for synthetic oriented organic chemists and for those, who want to get a first insight into the chemistry of selenium.

The pioneers of organoselenium chemistry realized that the chemistry of selenium-containing compounds offers multiple advantages over established methods. A wide range of reactions is possible, ranging from cationic, radical, and anionic transformations, to rearrangements and eliminations. Selenium-containing compounds can even be used as catalysts and ligands. The various findings in, and applications of, selenium chemistry has led, in recent years, to a tremendous growth which is reflected by the large number of publications in this field. However, the last comprehensive compilation of organoselenium chemistry appeared more than ten years ago.Embarking on a new millennium, we felt that there is a need for an update. I am grateful to the distinguished scientists who contributed, with their skill and expertise, the various chapters of this volume. By emphasizing the developments in organoselenium chemistry over the last number of years, this volume presents a comprehensive overview of the various facets, scope, and limitations of organic chemistry with selenium.
