An efficient and practical approach for the synthesis of sulfonyl quinolines via ball milling promoted coupling of haloquinolines with sulfonic acid under metal, solvent and additivefree conditions has been developed. In contrast to the solventbased sulfonylation reactions, this protocol has the advantage of sh 2021 Green Chemistry Hot Articles
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by both impact and abrasion. In ball milling, the ...

· Here we show that using solventless methods, such as ball milling, enabled the production of the hexapeptide Boc(AlaPheGly) 2 OBn at the gram scale with high overall yield (77%, 5 linear steps). This is the longest peptide chain synthesized in a ball mill to date, in which the amino acid sequence is precisely controlled. This study complements the current .

The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming effects. These ball mills are also suitable for mechano chemistry. Mixer Mills grind and homogenize small .
A mechanical ball milling method for ultrafast synthesis of a nickelbased metal organic framework (NiMOF) has been proposed. The NiMOF was successfully synthesized in merely one minute without any solvent, additives, or preliminary preparation. The effect of milling time, mechanofrequency, type of assistant liquid, and amount of assistant water were systematically explored.
