Book Description
Provides an account of the preparation, properties, and uses of the more important bi- and tri-cyclic ring systems incorporating the pyrazine ring. The first 18 chapters survey the developments in the chemistry of quinoxalines since the appearance in 1953 of a previous monograph in this series. The subsequent 22 chapters provide the first authoritative reviews of the chemistry of such important related ring systems as the pyrrolopyrazines.

Book Description
Nucleophilic aromatic substitution in carbo- and heteroaromatic systems is a subject of considerable interest to chemists. This book uniquely addresses the systematic analysis of a vast range of nucleophilic substitutions of aromatic hydrogen. Nucleophilic displacement of hydrogen (the S N/H reactions) in pi-deficient aromatics, such as nitroarenes, arene-metal complexes, and the like Nucleophilic displacement of hydrogen in heterocyclic substrates such as pyridines, their aza and benzo analogs, pyrylium and thiapyrylium cations, and other heterocycles Mechanisms for the S N/H reactions (S N/H(AE), vicarious nucleophilic substitutions, and radical S N/H substitutions

Book Description
The Uniqueness of Biological Materials deals with the unique properties of biological materials, carbohydrates, lipids, proteins, and nucleic acids and the extent to which this uniqueness is related to the uniqueness of life in general. More specifically, it examines whether the uniqueness of life is inherent in the material of living organisms. This volume is comprised of 32 chapters and begins with an introduction to the nature of biological uniqueness and how it is related to the uniqueness of life by comparing the elemental composition of living organisms with that of their environment. The discussion then turns to the uniqueness of hydrogen and oxygen which make up water; carbon; carbohydrates; and ternary compounds that are more fully oxidized than carbohydrates. Ternary compounds of intermediate grades of reduction are also considered, along with fatty acids and related lipids, paraffins, and olefins and ternary unsaturated compounds. Other biological materials discussed include peptides, proteins, amino acids, and halogens. This book will be of interest to students and practitioners of biology and biochemistry.
