Ball Milling - an overview ScienceDirect Topics

A study proposed the importance of ball milling in synthetic organic chemistry, which has been widely documented [110]. Many reports in the literature have shown that high-speed ball milling (HSBM) is appropriate for a variety of organic transformations and for the expansion of environmentally benevolent chemical reactions [111, 112] .

Synthesis of Metal Organic Frameworks by Ball-Milling -

2020-10-21  Ball milling is a method of small pollution, short time-consumption, and large-scale synthesis of MOFs. In recent years, many important advances have been made. In this paper, the influencing factors of MOFs synthesized by grinding were reviewed systematically from four aspects: auxiliary additives, metal sources, organic linkers, and reaction ...

Direct Amidation of Esters via Ball Milling Organic ...

2021-5-10  The direct mechanochemical amidation of esters – enabled by ball-milling – is herein described. The operationally simple procedure requires inputs of ester, amine, and sub-stoichiometric KOtBu and is applicable to a preparation of a large and diverse library of 78 amide structures with modest to excellent efficiency. Heteroaromatic and heterocyclic components are specifically shown to be ...

2019-12-20  Mixing solid reactants in a ball mill is a promising means of avoiding the copious solvent waste associated with most chemical syntheses. Kubota et al. now report that adding a piezoelectric catalyst to the mix can promote bond formation through apparent electron transfer cycles (see the Perspective by Xia and Wang). Specifically, barium titanate activates aryl diazonium salts toward ...

2019-5-25  Hybrid nanoparticles with a large bridging organic group were prepared by mechanochemical-assisted sol–gel reaction. Planetary ball mill (PBM) was used for the first time to access the bis-silylated precursors, containing complex functionalities (such as hydantoins or a symmetrical urea obtained from α-amino esters). The process is based on a sequential reaction

Solvent-Free Asymmetric Anhydride Opening in a Ball Mill ...

2007-2-10  The mechanochemical technique of ball milling has been applied to the asymmetric opening of meso-anhydrides, mediated by the cinchona alkaloid quinidine. A simple workup procedure affords the products, optically active dicarboxylic acid monoesters, in high yields, with up to 64% ee. With most substrates no column chromatography was needed. A range of various alcohols, as well as

Abstract. An operationally simple mechanochemical C-S coupling of aryl halides with thiols operates under benchtop conditions without the requirement for a (dry) solvent, an inert atmosphere, or catalyst preactivation. The reaction is finished within 3 h. The inclusion of zinc metal has been found to be critical for the coupling of alkyl thiols.
