THE CH/π INTERACTION
Evidence, Nature, and ConsequencesM. Nishio, M., Hirota, Y. Umezawa, 1998, Wiley-VCH, New York
ISBN-13: 978-0471252900
A systematic exploration of the fascinating area of CH/π interaction - from the frontier of chemical research.
The CH/π bond may be the weakest of the hydrogen bonds, but it has been found to play important roles in the physical, chemical, and biological properties of a variety of substances. This book offers a complete overview of the
experimental basis, theoretical background, and nature of the CH/π interaction to facilitate a clearer common understanding of the interaction between CH bond and π-systems.
Review by G. R. Desiraju (Chemistry in Britain, March 1999, p. 63)
The term 'CH-p interaction' was coined and popularized by Nishio and coworkers in two reviews that appeared in Tetrahedron in 1989 and 1995. This book is, in many ways, an extension of these reviews. With the current intense interest in molecular association, crystal engineering and other supramolecular phenomena, any book on intermolecular interactions is bound to attract attention. When the interaction is very feeble, its interpretation can become subjective and contentious. Given these difficulties, the authors have done a reasonable job. .....
..... A proper understanding of the gray area between the weak hydrogen bond and the van der Waals interaction is elusive and remains one of the more challenging goals in modern structural chemistry. This book is far from being the definitive work in the area but, all in all, researchers and students will find it interesting and purchase by libraries is generally recommended.
