Sustainable Catalysis Without Metals or Other Endangered Elements, Part

Sustainable Catal)fsis Without Metals or Other Endangered Elements, Part 1 

Asymmetric cyanohydrin synthesis remains an important reaction for organocatalysis and many of the catalyst classes discussed in subsequent chapters give highly effective catalysts for this reaction. These include Cinchona alkaloid derivatives, thioureas, guanidines, amine-oxides, diols and diamines.

Sustainable Catalysis Without Metals or Other Endangered Elements, Parts 1 and 2 deal with catalysts that do not possess a metal centre as part of their structure. After an introductory chapter. Chapters 2-4 cover non-asymmetric acid and base catalysis. The subsequent chapters (5-24) deal with asymmetric organocatalysis as this area has exploded in importance over the last 20 years. Again, catalysts that contain endangered elements e.g. phosphorus) have been excluded and authors were asked to highlight any examples that have other sustainable features (use of green solvent, high atom economy, etc.). 

Contained within this book are various chapters that review the possibilities for the sustainable use of catalysts in our chemical industiy. Earth abundant metals are discussed in Sustainable Catalysis With Non-endangered Metals, Parts 1 and 2, while the options for organocatalysis are discussed in Sustainable Catalysis Without Metals or Other Endangered Elements, Parts 1 and 2. The future chemical industiy cannot survive by the use of just one of the above catalyst classes, but will require the flexibility and versatility of both. An important aspect of sustainable catalysis that is also vital for the long-term security of elements is ensuring that we establish improved methods of catalyst recovery and reuse.
