The Porphyrins, Volume I: Structure and Synthesis, Part Ais the first in a series of seven volumes and covers topics like nomenclature, purification, and structural determination of porphyrins, metalloporphyrins, and other related compounds. This volume serves to be a critical review of the topics covered and presents a complete and comprehensible discussion on the chemistry and biochemistry of porphyrins. The chapters in the text tackle the history and geochemistry of porphyrins and related systems. Also covered and discussed in the chapters is the synthesis of porphyrins from mono-, di-, and tetrapyrrolic intermediates. The isolation and modification of porphyrins from natural sources are also discussed. Other related compounds are also included, such as metallo-, aza-, and N-methylporphyrins, and their synthesis and properties. This book is a good introduction and reference for students studying in the fields of chemistry and biochemistry.
