Chemistry of Heterocyclic Compounds

This book offers a simplistic but comprehensive overview of heterocyclic compounds. The first two chapters deal with introduction, nomenclature and significance of heterocyclic compounds. The subsequent chapters explicitly provide various methods of preparation and reactivity of three to seven membered heterocyclic compounds. The Physical properties such as boiling point, melting point, dipole moment and pKa as well as spectral data (1H and 13C NMR) of three to seven membered heterocyclic compounds are included in respective chapters. Each chapter ends with questions and their answers or hints that illustrates the concept at hand. The mechanism of important reactions has also been included at the appropriate places. This book will be useful for professors of chemistry, researchers working in various laboratories and students preparing for competitive exams. Contents 1. Introduction and Nomenclature 2.
