The development of catalysts for important chemical transformations certainly predates any notion of green chemistry and has been a major feature of research in all areas of chemistry for almost 150 years. Thus, physical chemists and material scientists have dominated the development of heterogeneous catalysis; physical and physical organic chemists have developed tools to allow catalytic cycles to be determined. Inorganic and organic chemists have developed new ligands and catalysts for homogeneous metal-based catalysts and organic chemists have shown that metal-free asymmetric catalysis can be achieved. Finally, biological chemists have studied the mechanisms of enzyme-catalysed reactions and developed new biochemical tools that allow the structure of enzymes to be modified to enhance their catalytic activity for a particular substrate, or even allow them to catalyse a different reaction. There have been some remarkable achievements in catalyst development recognisedbynumerousNobelprizesforworkdoneinthisarea(Box3)and catalysis has progressed to the stage where it is now difficult to imagine a reaction that cannot be achieved catalytically. However, examination of the catalyticliteratureshowsthatthemajorityofcatalystsdeveloped,andmany that are in commercial use rely upon the use of metals or other elements whose abundance in the Earth’s crust is very limited and that are being rapidly consumed. This is illustrated in Figure 1 for papers on asymmetric catalysis published between 1999 and 2005.3 RSCGreenChemistryNo.38 SustainableCatalysis:WithNon-endangeredMetals,Part1 EditedbyMichaelNorth rTheRoyalSocietyofChemistry2016 PublishedbytheRoyalSocietyofChemistry,www.rsc.org vii viii Preface Box 1 The 12 principles of green chemistry according to Anastas 1. Itisbettertopreventwastethantotreatorcleanupwasteafteritis formed. 2. Synthetic methods should be designed to maximise the in- corporation of all materials used in the process into the final product. 3. Whereverpracticable,syntheticmethodologiesshouldbedesigned to use and generate substances that possess little or no toxicity to human health and the environment. 4. Chemical products should be designed to preserve efficacy of function while reducing toxicity. 5. The use of auxiliary substances (e.g. solvents, separation agents etc.) should be made unnecessary wherever possible and innocu- ous when used. 6. Energy requirements should be recognized for their environ- mentalandeconomicimpactandshouldbeminimized.Synthetic methods should be conducted at ambient temperature and pressure. 7. A raw material or feedstock should be renewable rather than de- pleting wherever technically and economically practicable. 8. Unnecessary derivatization (blocking group, protection/deprotec- tion, temporary modification of physical/chemical processes) should be avoided whenever possible. 9. Catalytic reagents (as selective as possible) are superior to stoi- chiometric reagents. 10. Chemical products should be designed so that at the end of their function they do not persist in the environment and break down into innocuous degradation products. 11. Analyticalmethodologiesneedtobefurtherdevelopedtoallowfor real-time,in-processmonitoringandcontrolpriortotheformation of hazardous substances. 12. Substancesandtheformofasubstanceusedinachemicalprocess should be chosen so as to minimise the potential for chemical accidents, including releases, explosions and fires. The availability of chemical elements depends on many factors as discussed in Chapter 1 of Sustainable Catalysis: With Non-endangered Metals,Part1.Withtheexceptionofhelium,whichistoolighttobeheldby the Earth’s gravity and so is lost to space, chemical elements are not actually being lost to planet Earth, rather they are being transferred from relatively rich ores to much more diluted waste sites from where, in most Preface ix Box 2 The green chemistry mnemonic developed by Poliakoff P – Prevent wastes R – Renewable materials O – Omit derivatization steps D – Degradable chemical products U – Use safe synthetic methods C – Catalytic reagents T – Temperature, pressure ambient I – In process monitoring V – Very few auxiliary substances E – E-factor, maximise feed in product L – Low toxicity of chemical products Y – Yes, it is safe cases, it is not currently economically viable to recover them. This, combined with growing demand for many elements, often low recycling ratesandgeographicalandpoliticalrestrictionsonoreavailabilityleadsto the concept of elemental sustainability. One pictorial representation of elemental sustainability is shown in Figure 24 and this, along the British GeologicalSurvey2012Risklist(BGS2012)5whichrankedthesupplyriskof elements from10(high)to 1(low) forms thebasisof therestofthis book. Thus, catalysts that contain only elements coloured green or orange in Figure 2 and that have a relative supply risk index of 7.6 or lower in the BGS2012areincludedinthisbookwiththreeexceptions.Palladiumwould have been borderline to include (orange in Figure 2 and supply risk index of7.6inBGS2012),buthasbeenexcludedasitissowidelyusedincatalysis that it would have required a separate volume to cover its use in catalysis. Achapteronscandiumandyttriumbasedcatalystswasplannedbutcould not be delivered due to the author’s ill health. After an introductory chapter on elemental sustainability, the first two volumes of this work, Sustainable Catalysis: With Non-endangered Metals, Parts 1 and 2, deal with sustainable metal based catalysts. Within each subsequentchapter,theauthorshavebeenaskedtoexcludeanycatalystthat contains ligands containing endangered elements (e.g. phosphorus) and to highlight any examples that have other sustainable features (use of green solvent, high atom economy, etc.). Where appropriate, elements have been grouped together (e.g. thealkali metals inChapter 2) and those metals that are most commonly used in catalysis have been given multiple chapters: Chapters 4–7 for titanium, 12–13 for iron and 18–19 for aluminium.
