Kurzbeschreibung Flash chemistry is a new concept which offers an integrated scheme for fast, controlled organic synthesis. The first book to describe this exciting new technique, Flash Chemistry brings together research in reactive intermediates and microreactors into an integrated scheme for fast, controlled organic synthesis. This key text provides an essential introduction for anyone working in related fields, including chemists, and advanced undergraduate and postgraduate organic chemistry students.
