Although poisonous substances have been a hazard for the whole of human history, it is only with the development and large-scale production of new chemical substances over the last two centuries that toxic, manmade pollutants have become such a varied and widespread danger. Covering a host of both notorious and little-known chemicals, the chapters in this collection investigate the emergence of specific toxic, pathogenic, carcinogenic, and ecologically harmful chemicals as well as the scientific, cultural and legislative responses they have prompted. Each study situates chemical hazards in a long-term and transnational framework and demonstrates the importance of considering both the natural and the social contexts in which their histories have unfolded.
Science of Synthesis: Flow Chemistry in Organic Synthesis
The aim of this work is to convey the practice, power, and potential of flow chemistry to a larger audience. An emerging and strengthening trend is that flow chemistry is much more than the adaption of batch processes to flow systems. Rather, flow chemistry offers a new paradigm in the way we think about chemical synthesis. This volume demonstrates the enabling power of continuous flow to access new reaction types and different chemistry space and, to this end, it has been compiled by a team of pioneers and leaders, who present both the practical and conceptual aspects of this rapidly growing field. Included are the principles of reactor design, automation, and separations/purifications in flow systems, applications in photochemistry, electrochemistry, gaseous systems, immobilized reagents and catalysts, and multistep processes. The synthesis of peptides, carbohydrates, and pharmaceuticals is covered and several chapters give insight into the use of flow in an industrial context.

Science of Synthesis: Catalytic Reduction in Organic Synthesis Vol. 2
Catalytic reductions are among the most used synthetic transformations, and the past 15 years have seen great progress in this field. Science of Synthesis: Catalytic Reduction in Organic Synthesis includes the latest developments, as well as selective coverage of more well-established methods. Both heterogeneous and homogeneous catalytic systems are covered, and enantioselective methodology is well represented. There is a focus on the use of metal nanoparticles, both in suspension as well as on solid supports. Furthermore, the advent of research on the conversion of renewable resources into fuels and chemicals has given a great impetus to the field, as deoxygenations are often the first step in the conversion of biomass and this can often be achieved using hydrogenation or hydrogenolysis reactions. Scope, limitations, and mechanism of the reactions are discussed and key experimental procedures are included.

Science of Synthesis: N-Heterocyclic Carbenes in Catalytic Organic Synthesis Vol. 1
The field of N-heterocyclic carbenes, whether in transition-metal catalysis or organocatalysis, is rapidly evolving towards applications, but is also still very active on the catalyst development front. Significant advances have been made over the past two decades and the development of these reactions has dramatically improved the efficiency of organic synthesis. N-Heterocyclic carbene based catalysts are now widely applied in the area of synthesis of both natural products and therapeutic agents. Science of Synthesis: N-Heterocyclic Carbenes in Catalytic Organic Synthesis presents the most commonly used and significant metal- or non-metal-catalyzed reactions for modern organic synthesis. The basic principles and current state-of-the-art of the methods are covered. Scope, limitations, and mechanism of these reactions are discussed and key experimental procedures are included. Typical examples of target synthesis are often provided to show the utility and inspire further applications.
