Waste minimisation has a number of aims which include enhancing the intrinsic selectivity of any given process, providing a means of recovering reagents in a form which allows easy regeneration and the replacement of stoichiometric processes with catalytic ones. Solids, as catalysts or as supports for other reagents, offer potential for benefit in all these areas. This monograph provides an overview of the properties of the more useful solid catalysts and supported reagents, and highlights their most valuable applications in the preparation of organic chemicals in liquid phase reactions....
