Editorial Reviews

`... provides a well-organized discussion of a large number of tautomeric transformations, many of them observed only during the last ten years.' `Overall, this is a highly useful and timely textbook that makes interesting reading for advanced undergraduate and graduate students in (physical) organic chemistry. The book is recommended, not only for personal purchase, but also for inclusion in all major chemical library collections.' Recueil des Travaux Chimiques des Pays-Bas, Vol. 107, No. 5, May 1988
