A Ball‐Milling‐Enabled Reformatsky Reaction - Cao - 2019 ...

An operationally simple one‐jar one‐step mechanochemical Reformatsky reaction using in situ generated organozinc intermediates under neat grinding conditions has been developed. Notable features of this reaction protocol are that it requires no solvent no inert gases and no pre‐activation of the bulk zinc source.

Mechanochemistry drops the ball in MOF synthesis ...

Friščić’s team has gone a step further by also removing the need for so-called grinding media – the tiny balls or pellets used to grind the molecules together. Traditional mechanochemical methods like ball milling can cause contamination – a particular problem for products that rely on their purity like pharamaceuticals.

Effects of Quartz Addition on the Mechanochemical ...

Grinding a mixture of 3-chlorobiphenyl BP-Cl and CaO with or without the addition of quartz was conducted in air by a planetary ball mill to investigate the mechanochemical dechlorination of BP-Cl. The dechlorinating reaction proceeds with an increase in grinding time and over 99 of BP-Cl is decomposed at 360 min. Washing the ground sample with different solvents results in different ...
