Vinyl Cations provides a comprehensive and detailed treatment of the reactive intermediate in which the electron-deficient carbon is an integral part of a? unsaturation. This book emphasizes that the reaction through vinyl cations is a viable pathway among the multitude of mechanistic routes for vinylic substitution. The aryl, ethynyl, and allenyl cations from the viewpoint of direct solvolytic generation from appropriate allenyl precursors are briefly discussed. Other topics include the preparative aspects of electrophilic additions to alkynes, participation of allenyl bonds in solvolyses, and vinyl cations generated through diazonium ions. The nature of the cationic intermediates, migrations across the double bond, thiirenium ions, and species related to vinyl cations are likewise elaborated. This publication is beneficial to chemists and researchers concerned with vinyl cations.

This reference details the theory and application of cation complexation, including the design and synthesis of various cyclic systems, these materials'use as transport systems, in complexation and selectivity studies by macrocyclic systems, and methodologies for understanding these phenomena.
