The simplicity and effectiveness of this mechanochemical approach make it a promising tool for advancing greener synthetic practices in both academic and industrial settings. Its rapidity, efficiency, and environmentally friendly nature offer a distinct advantage over traditional methods, contributing to a more sustainable future in synthetic chemistry. , and NMI (15 mol%) were ball milled for 1 minute, then IV was added and shaking was continued for 3 x 5 minutes at 36 Hz, with opening the vessels every 5 minutes. The pre-formed ylide (obtained by milling PPh3MeBr (0.9 mmol, 1.8 equiv.) and KO t Bu (0.8 mmol, 1.6 equiv.) for 1 min at 36 Hz) was added and milling was continued for 1 minute at 36 Hz (for details, see SI).
