Direct Amidation of Esters by Ball Milling**

Angewandte Chemie - International Edition, 2021
Abstract The direct mechanochemical amidation of esters by ball milling is described. The operationally simple procedure requires an ester, an amine, and substoichiometric KOtBu and was used to prepare a large and diverse library of 78 amide structures with modest to excellent efficiency. Heteroaromatic and heterocyclic components are

Ball‐Milling‐Enabled Reactivity of Manganese Metal** [PDF]

open access: yesAngewandte Chemie - International Edition, 2021
AbstractEfforts to generate organomanganese reagents under ball‐milling conditions have led to the serendipitous discovery that manganese metal can mediate the reductive dimerization of arylidene malonates. The newly uncovered process has been optimized and its mechanism explored using CV measurements, radical trapping experiments, EPR spectroscopy ...

Slurry density effects on ball milling in a laboratory ball mill

Powder Technology, 1989
Abstract The effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material. It was found that slurry density determined the distribution of solid charge in the mill, with migration of particles from the tumbling zone to the mill periphery as solid concentration was progressively ...

Phases in ball-milled

Journal of Physics: Condensed Matter, 1997
Phases in ball milled for different lengths of time have been investigated by means of x-ray diffraction, Mossbauer spectroscopy and Raman scattering spectroscopy. It was found that the high-temperature phase can be formed by ball milling at room temperature. In the milling procedure the compounds FeSi and were also formed.
