Pericyclic Reactions,Volume 35-II covers the theoretical approaches to pericyclic reactions and reviews of pericyclic reactions of reactive intermediates and of particular reaction types. The book discusses some of the experimental approaches used to establish the authenticity of an apparent pericyclic reaction; the transient and observable carbocation rearrangements; and orbital symmetry interactions which are "extra¿ stabilizing or destabilizing. The text then describes the pericyclic reactions of cumulenes; the cheletropic reactions; the applications of frontier molecular orbital theory to pericyclic reactions. A general theoretical model accommodating concerted reaction profiles for forbidden thermal reactions is also encompassed. Chemists and people involved in the study of pericyclic reactions will find the book invaluable.
