We describe the nearly quantitative preparation of phosphorus ylides and the Wittig reaction occurring in the solid sate during high-energy mechanochemical processing. Initial insights into the details of the discovered chemical transformations indicate that high-energy mechanical processing supports the interaction of reacting centers by breaking crystallinity of the reactants and by providing...

The accumulation and disposal of polymer wastes including waste plastics, waste rubber, waste synthetic fibers and waste composites is a worldwide concern. Until now, there are many technical barriers in recycling polymer wastes with crosslinked structure, such as vulcanized rubber, crosslinked polyolefine and other thermoset materials. In this study, a mechanochemical approach was used to cond...
