The large-scale production of chemicals to meet various societal needs has created environmental pollution, including pollution from byproducts and improper disposal of waste. With the world facing adverse consequences due to this pollution, green chemistry is increasingly being viewed as a means to address this concern. Since most organic syntheses require toxic solvents, more reaction time, and drastic conditions of temperature, conventional methods of organic synthesis are less preferred. Microwave-assisted organic synthesis is considered to be a promising green chemical approach because it reduces reaction time from days or hours to minutes or even seconds, and has many other advantages. It helps reduce side reactions and increase yields, uses fewer solvents or is almost solvent-free, has solid supported reactions, and improves purity. This book’s main focus is microwave-assisted organic synthesis processes, particularly various reactions such as cycloaddition, rearrangement, elimination, substitution, oxidation, reduction, condensation, coupling, polymerization, nanomaterials, synthesis of heterocycles, and industrial applications under microwave irradiation. The time is not far off when this methodology will virtually replace existing and cumbersome methods of organic synthesis.

The principal aim of this book is to introduce chemists through a tutorial approach to the use of microwaves by examining several experiments of microwave chemistry and materials processing. It will subsequently enable chemists to fashion their own experiments in microwave chemistry or materials processing. Microwave heating has become a popular methodology in introducing thermal energy in chemical reactions and material processing in laboratory-scale experiments. Several research cases where microwave heating has been used in a wide range of fields have been reported, including organic synthesis, polymers, nanomaterials, biomaterials, and ceramic sintering, among others. In most cases, microwave equipment is used as a simple heat source. Therefore the principal benefits of microwave radiation have seldom been taken advantage of. One reason is the necessity to understand the nature of electromagnetism, microwave engineering, and thermodynamics. However, it is difficult for a chemist to appreciate these in a short time, so they act as barriers for the chemist who might take an interest in the use of microwave radiation. This book helps to overcome these barriers by using figures and diagrams instead of equations as much as possible.

The first reports on the application of microwaves in organicsynthesis date back to 1986, but it was not until the recentintroduction of specifically designed and constructed equipment,which countered the safety and reproducibility concerns, thatsynthetic application of microwaves has become established as alaboratory technique. Microwave assisted synthesis is now beingadopted in many industrial and academic laboratories to takeadvantage of the novel chemistry that can be carried out using avariety of organic reaction types. This book demonstrates the underlying principles of microwavedielectric heating and, by reference to a range of organic reactiontypes, it's effective use in synthetic organic chemistry. Toillustrate the impact microwave assisted organic synthesis can haveon chemical research, case studies drawn mainly from thepharmaceutical industry are presented.

We are delighted to present this volume with contributions from some of the most renowned and experienced microwavechemists today. The delivery and introduction of energy has been closely connected with the discovery and investigation of new chemistry. It is with pleasure that we have seen an increased use of microwave irradiation over the years and we hope that this volume will re?ect the current interest in expanding the scopeofmicrowaveapplicationsinbothorganicandmedicinalchemistry. One important explanation behind the growth of microwave-enhanced chemistry has been the introductionof dedicated microwavereactors. As a result of this development we are proud to present a diverse set of - views. Apart fromchapters spanning the scope that is usually associated with microwavemethods, such as heterocyclic chemistry – an intriguing, but fr- tratingly diverse?eld that is excellently presented in one of the reviews – and transition metal-catalyzed reactions, we also present a review on microwa- assisted natural product chemistry, a topic that is of high interest and neither often nor widely covered. A contribution on microwave-accelerated synt- sis of protease inhibitors underlines the usefulness of microwave heating in medicinal chemistryandareview of?uorousmicrowavechemistryhighlights the importance of the combination of high-speed reactions and quick sepa- tions. Two separate chaptersonscaled-up microwavereactionsandgreen and sustainablechemistrygiveanoverviewofaspectsofmicrowavechemistrythat mightbeofgreatuseinbothindustrialandsmall-scaleapplications. We would like to take this opportunity to express our sincere gratitude to the contributors of this volume for their valuable time and efforts. We believe that the presented workwill further promotethe use of controlledmicrowave heating in both academia and industry.
