Description
Book SynopsisUnique in its focus on preparative impact rather than mechanistic details, this handbook provides an overview of photochemical reactions classed according to the structural feature that is built in the photochemical step, so as to facilitate use by synthetic chemists unfamiliar with this topic. An introductory section covers practical questions on how to run a photochemical reaction, while all classes of the most important photocatalytic reactions are also included.
Perfect for organic synthetic chemists in academia and industry.
Trade Review"Given its organization and practical emphasis, I believe that this book would make an outstanding addition to the library of any synthetic organic chemist. It should certainly be on the acquisition lists of all institutional libraries." (Journal of the American Chemical Society, November 2010)
