Mechanochemical Nalkylation of imides

Here, imide 1 is a solid, while dibromopropane is a liquid reagent. It was found that during the ball-milling process (Retsch MM400 mill at 30 Hz, stainless steel 10 mL vial, one 12 mm steel ball) of this solid/liquid system, mono-alkylation and formation of imide 3 was accompanied by the bisalkylated product 4 .
