Oxocarbons is a 10-chapter text that covers chemical-physical aspects, reaction chemistry, and spectroscopic investigations of oxocarbons. This book starts with a discussion on the early history of the oxocarbons. The subsequent seven chapters are devoted to the reactions, synthesis, and chemistry of substituted derivatives of cyclic polycarbonyls, called ""pseudooxocarbons"". The remaining chapters describe the structural phase transition and dielectric properties of squaric acid. This book will be of value to organic chemists and researchers who are interested in the synthesis of oxocarbons and related derivatives.
