The demands for green and sustainable synthetic methods in the fields of healthcare and fine chemicals, combined with the pressure to produce these substances expeditiously and in an environmentally benign fashion, pose significant challenges to the synthetic chemical community. Green chemistry can avoid pollution by utilizing techniques that are environmentally friendly by design and one of the best green techniques is the use of microwave (MW) assisted aqueous synthetic protocols. Fusing MW technique with water (as a benign reaction medium) can offer an extraordinary synergistic effect with greater potential than these two individual components in isolation. Selective microwave heating can be exploited to develop a high yield protocol and the use of water expedites the MW-protocol with more energy efficiency. This book provides an overview of the various processes developed using aqueous microwave chemistry and is written for chemists, chemical engineers and researchers in the early stages who want to develop sustainable and green processes. Written by well known microwave experts, the book is a comprehensive examination of the field and is the first book that deals strictly with aqueous microwave chemistry and represents a significant effort towards green chemistry. It covers all the microwave-assisted aqueous reactions in depth, including heterocycle synthesis, metal catalysis, enzyme catalysis, polymer synthesis, nanomaterials synthesis and nano-catalysis. Each chapter contains representative experimental procedures, helping the reader quickly replicate some of the experiments to gain hands-on experience.

The first reports on the application of microwaves in organic synthesis date back to 1986, but it was not until the recent introduction of specifically designed and constructed equipment, which countered the safety and reproducibility concerns, that synthetic application of microwaves has become established as a laboratory technique. Microwave assisted synthesis is now being adopted in many industrial and academic laboratories to take advantage of the novel chemistry that can be carried out using a variety of organic reaction types. This book demonstrates the underlying principles of microwave dielectric heating and, by reference to a range of organic reaction types, it’s effective use in synthetic organic chemistry. To illustrate the impact microwave assisted organic synthesis can have on chemical research, case studies drawn mainly from the pharmaceutical industry are presented.

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 series Advances in Polymer Science presents critical reviews of the present and future trends in polymer and biopolymer science. It covers all areas of research in polymer and biopolymer science including chemistry, physical chemistry, physics, material science.The thematic volumes are addressed to scientists, whether at universities or in industry, who wish to keep abreast of the important advances in the covered topics.Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic, and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles, and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist.Review articles for the individual volumes are invited by the volume editors. Single contributions can be specially commissioned.Readership: Polymer scientists, or scientists in related fields interested in polymer and biopolymer science, at universities or in industry, graduate students

For more than a century, heterocycles have played a crucial role in the biological and industrial development of society, becoming one of the most researched areas within organic chemistry. The first chapter of Microwave-Induced Synthesis of Aromatic Heterocycles is based on microwave theory, the latest developments in instrumentation technology, and the various microwave technologies used for synthesis. The remainder of the chapters are divided into two sections. Section A deals with the five-membered heterocycles (pyrazoles, isoxazoles, triazoles, oxadiazoles, thiazoles, imidazoles, oxazoles, oxazolines etc.) and in Section B, various six-membered heterocycles (triazines, benzoxazoles, benzimidazoles, benzothiazoles) are presented. Both sections contain a detailed, recent literature review of microwave assisted synthesis and its applicability to various aromatic heterocyclics.
