'[This book] will remain a classic for researchers, professors, and students and a must for everyone working in organometallic Chemistry and Catalysis.' Bruno Chaudret, Director de Recherche, Laboratoire de Chimie de Coordination 'This new book provides an excellent source of information on the formation, structures, and reactions of Metal Dihydrogen and sigma-Bond Complexes. The presentation is clear, comprehensive and up-to-date. This thorough and readable book should be on the shelves of scientific libraries and individual chemists interested in inorganic, catalytic and physical chemistry.' D.F. Shriver, Morrison Professor of Chemistry, Northwestern University '[An] excellent and comprehensive treatise...a true expert in the field of metal-hydrogen chemistry.' John P. Fackler, Jr., Distinguished Professor of Chemistry, Texas A&M University 'The reactions of transition metals and metal complexes with hydrogen, and also hydrocarbons, were already very important fields of study with applications in large scale industrial catalysis and energy storage and conversion. These useful reactions are now viewed in a new light thanks to the emergence of the new concept of sigma-complex chemistry as described clearly and comprehensively by Greg Kubas in this book.' Robert H. Morris, Professor of Chemistry, University of Toronto 'This book will be of use to persons whose research interests include the subject matter of the book, but I also recommend sections of it more broadly... I strongly recommend the book for those who are involved in the field. It is very well written...' Ray L. Sweany, University of new Orleans in Journal of the American Chemical Society 'I strongly recommend the book for those who are involved in the field. It is very well written, and for those who are worried about the time delay between the onset of the writing and the publication, some references come from as late as the latter half of 2000' J.AM.Chem. Soc., 124:14 (2002)
