Synthesis is the preparation of substances by way of chemical processes. These processes generally involve several chemical (and/or biochemical) reactions. Chemical synthesis activities can be either process-focused or product-focused. In process-focused work, new ways are developed to create specific types of covalent bonds. In product-focused studies, new ways to form entire molecules are invented. Chemical synthesis is an integral part of the majority of work carried out at the RSC: for some groups, synthesis is used to make substances for study; for other groups, the chemical synthesis itself is the focus of their work. Those working on advancing the science of synthesis aim to make synthesis more efficient and of broader scope, in a safer way with lower environmental impact.
