Mechanochemistry as a green method in organic chemistry and its applications

Abstract Activation of chemical reactions in the solid state by mechanical energy represents a novel method with a high potential to be used in organic chemistry and various applications. There are several advantages over the classical reactions which are carried out in solution. Green aspects are in the avoidance of organic solvents, which diminishes environmental impact, whereas shortening of reaction times and room temperature conditions reduce the energy input. Furthermore, mechanochemical reactions could lead to products which cannot be obtained by solution chemistry or are produced by higher atom efficiency. The realization of the simplicity of the method and its advantages by chemists has led to increased application. The basics of the method and selected reactions are illustrated, in order to introduce this environmentally friendly method and to widen its use by the organic science community.
