(Figure Presented) Waste not want not: A [2]rotaxane has been generated in 49% yield through the direct grinding of solid macrocyclic, threadlike, and stoppering components. The same solid-state ball-milling reactions of solids of pseudorotaxanes and stoppers produced both [2]- and [4]rotaxanes in high yield (see picture). The approach relies on solid-state condensations and is convenient and waste-free (water is the only by-product).
