Present Status and Future Outlook

Abstract

Sustainable, modern societies require significant progress toward sustainable technologies, industries, and products. Solvent-free methods, which are of great interest in a vast range of catalyst synthesis, have added value to material manufacturing, and many essential industrial organic synthesis and transformations can offer economically viable alternatives for classical procedures. Moreover, they can modernize classical technologies and organic reactions toward environmental sustainability, making them cleaner, safer, and more efficient. Simultaneously, with proper tailor-made catalyst employment, further noticeable increases in reactivity and selectivity can be expected under mild/short reaction conditions minimizing the number of reaction steps, waste formation and providing a high atom economy. The proposed contribution aims to provide a summary of the present status and future outlook for solvent-free methods considering both (i) solvent-free synthesis of advanced materials, i.e. catalysts, and (ii) solvent-free reactions.
