ACS Sustainable Chemistry & Engineering Virtual Special Issue—Mechanochemistry

Starting with stone mortars and pestles, before history was ever written, humans have ground and milled materials to induce physical or chemical changes. In the modern world, the systematic study of such processes has given rise to the field of mechanochemistry, set apart from its peers by the preferential use of solid-state reagents. At the roots of mechanochemistry lies the ability of solids to support shear strain. Unlike fluids, sheared solids under stress experience a distortion of their crystalline structures. The resulting modification of crystal geometries can induce destabilization of chemical bonds in covalent, ionic, and metallic solids, and symmetry breaking in molecular solids, which can eventually cause chemical transformations.

Driven by scientists’ enthusiasm and by the promise of genuinely revolutionary impacts on the industrial preparation of fine chemicals and pharmaceuticals, mechanochemistry is slowly but steadily overcoming practical limitations (such as issues of scale-up), and its potential benefits are becoming ever more apparent. Mechanochemistry’s increased adoption promises a bright future of enhanced sustainability for the chemical industry, providing feasible solutions to realise the United Nations Sustainable Development Goals and the European Green Deal objectives.

In recent years, the use of mechanochemical methods to induce and alter chemical transformations has gained remarkable momentum, particularly in the field of organic synthesis. This Virtual Special Issue (VSI) concerning Advances in Mechanochemistry features contributions from prominent scientists in the area and is particularly focused on mechanochemical methods for enabling sustainable synthetic routes.
