Chemical industries have to face the big challenge of finding adequate processes to produce large quantities of new products for which there is a present need, decreasing at the same time both the impact on the environment and the risk of disasters. These issues have led to the establishment of new concepts of sustainable development as affirmed in the Rio Declaration on Environment and Development in the early 90s and has been the subject of intensive studies in the last two decades. The book addresses this challenge collecting the recent New Methodologies and Techniques for a Sustainable Organic Chemistry. It provides a wealth of information in the fields of - New efficient and selective catalytic processes - Use of non-usual media or environmentally benign reagents - New selective and efficient synthetic methods - New techniques based on alternative energy sources. All these topics are covered in 15 chapters written by world-renowned experts in these fields who were the lecturers of the NATO ASI NeMeTOC (2005, Siena). Since some of the authors have an industrial background, the book helps to answer virtually any questions which may arise during the development of a new environmentally benign organic process.
